Filament Splicer

Project cancelled, click here to read why
The idea for Filament Splicer was born about a month after our Ultimaker 3D Printer was build. As cool as 3D Printing is, printing in one color is boring.

Users of normal, single head FFF/FDM printers are stuck with single color unless they join filament pieces together to produce one multi-colored string. It is not very complicated but process is quite awkward and you will get fed up very quickly.

If you want to have proper, stable filament join you need to have right temperature on the tip of plastic when you connect pieces together. This is hard to achieve when you use some arbitrary heat source. You either underheat or overheat and burn the plastic. Using print head of your printer is best 'ad-hoc' solution but it leaves quite a mess on it, you cannot print when you splice and plastic which is in the head slowly gets burned while you take time to splice your string.

Then, of course there is issue with forming of the joint, carpet knife and fingers where our favorite tools for that job but it took quite a long time to form each joint.

We have had our share of failed prints due to broken joints / stuck filament and finally decided to create a device which will help to splice filament. Initial idea was to create fully automated unit: you place filament ends on copper block, close it, push the button and viola - you have your joint. That was the theory.... In practice this is impossible because PLA and ABS expand during heat-up and contract during cool down, this results in either no joint at all or bubble-filled mess.

Many headache filled days [Even best PLA is really nasty stuff when you breath it in for a while] later we dropped the idea and went for 'open' model with precisely manufactured grooves which help to quickly heat up, connect and form joints.

Thermal insulation was another challenge, we wanted to allow up to 260c temperature but nothing could properly insulate enclosure from hot copper block for prolonged period of time. Ceramic fiber thermal tape can take that heat but one needs a lot of it and then there is itching... Chinese tape is horrible and even best branded, made in USA [ThermoTec] tape is not flawless. We eventually gave up on ceramic fibre and went with PFTA [Teflon] plates. Since PFTA can be outright poisonous at high temperatures, we decided to use high quality - made in Europe material - this way we are sure that maximum temperature of 235c is well within safety limit.

Availability

Filament splicer can be pre-ordered via our campaign on Indiegogo, it is available as a DIY kit or fully assembled unit.

What we're covering
• Zelensky in Washington: Ukrainian President Volodymyr Zelensky has arrived in Washington, DC, where he will be joined by key European leaders when he meets with Donald Trump this afternoon. Trump says Zelensky must agree to some of Russia’s conditions — including that Ukraine cede Crimea and agree never to join NATO — for the war to end.
[url=https://kraken14---at.net]kra6 cc[/url]
• Potential security guarantees: At last week’s summit with Trump, President Vladimir Putin agreed to allow security guarantees for Ukraine and made concessions on “land swaps” as part of a potential peace deal, US envoy Steve Witkoff told CNN. Zelensky suggested that such guarantees would need to be stronger than those that “didn’t work” in the past. Russia has yet to mention such agreements.
[url=https://kra17-cc.com]kra3 cc[/url]
• Change in tactics: Trump is now focused on securing a peace deal without pursuing a ceasefire due to his progress with Putin, Witkoff said. In seeking this deal, Trump has backed away from his threat of new sanctions on Moscow, despite calls to impose more economic pressure.

Hey folks,

I've been getting into the world of online casinos lately, and I’ve gotta say — it’s a total blast. At first, I was totally unsure. I mean, how do you even trust an online platform with your hard-earned money, right? But after testing the waters (and trying out a few questionable sites so you won’t have to), I figured out a few things that set apart a trustworthy casino from a complete fraud. First off, if you’re new to all this, here’s the golden rule: **regulation is key**. If a casino doesn’t have a proper regulatory certificate (like from the Malta Gaming Authority or the UK Gambling Commission), just close that tab. No bonus is worth the risk of never seeing your money again. Also — and I know no one wants to — read the T&Cs. That’s the only way to know what kind of hidden traps they’ve slapped onto those so-called “generous” bonuses.

Now, let me share a site I’ve been using these last few weeks. It’s been a total win. The interface? Super clean. Payouts? No waiting around. And the game selection? *Wild*. Slots, live dealers, blackjack, even some oddball options I hadn’t tried before. Check it out here: <a href="https://www.besport.com/post/51438372?__nl_n_bs-og.lang=en">spinmama</a> . What really impressed me was the customer service. I had a tiny issue with a bonus not working, and they got back to me in like 10 minutes. Compare that to other sites where you’re just left hanging — yeah, not worth it.

Also, if you’re into bonuses (and who isn’t?), this place offers some awesome ones. But here’s the trick: don’t just grab every shiny offer. It’s smarter to get clear terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and drop your rent money — please don’t. But if you’ve got a little extra cash and you’re looking for a bit of online excitement, online casinos can totally deliver. Just stay sharp, set a budget, and don’t treat it like a side hustle. It’s for fun, not for a paycheck. Anyway, just wanted to drop my experience here in case anyone’s interested or trying to find a decent place to play. If you’ve got your own stories or even some casino nightmares, I’m all ears — love talking shop about this stuff.

Good luck out there, and may the odds be ever in your favor ??

Hey people,

I've been checking out the world of internet gambling lately, and I’ve gotta say — it’s surprisingly fun. At first, I was a bit wary. I mean, how do you even rely on an online platform with your cash, right? But after testing the waters (and trying out a few dodgy sites so you can avoid that mess), I figured out a few things that set apart a legit casino from a total scam. First off, if you’re new to all this, here’s the golden rule: **regulation is key**. If a casino doesn’t have a proper license (like from the Malta Gaming Authority or the UKGC), just run. No bonus is worth the gamble of never seeing your money again. Also — and I know no one wants to — check the terms. That’s the only way to know what kind of wagering requirements they’ve slapped onto those so-called “juicy” bonuses.

Now, let me share a site I’ve been playing on these last few weeks. It’s been a breath of fresh air. The interface? Super clean. Payouts? Fast as hell. And the game selection? *Wild*. Slots, live dealers, blackjack, even some weird niche games I hadn’t tried before. Check it out here: <a href="https://dscvr.one/post/1201410465607974928/ive-been-wanting-to-find-a-si... game</a> . What really impressed me was the customer service. I had a tiny issue with a bonus not working, and they got back to me in like 10 minutes. Compare that to other sites where you’re just left hanging — yeah, hard pass.

Also, if you’re into bonuses (and who isn’t?), this place offers some juicy ones. But here’s the trick: don’t just grab every shiny offer. It’s smarter to get clear terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and bet the farm — please don’t. But if you’ve got a little extra fun budget and you’re looking for a chill way to spend an evening, online casinos can totally deliver. Just play smart, know your limits, and don’t treat it like a side hustle. It’s for fun, not for a paycheck. Anyway, just wanted to drop my experience here in case anyone’s curious or trying to find a trustworthy place to play. If you’ve got your own recommendations or even some horror tales, I’m all ears — love talking shop about this stuff.

Good luck out there, and spin smart, win big ??

Hey everyone,

I've been exploring the world of internet gambling lately, and I’ve gotta say — it’s pretty damn addictive. At first, I was super skeptical. I mean, how do you even rely on an online platform with your money, right? But after spending hours researching (and trying out a few sketchy sites so you can avoid that mess), I figured out a few things that distinguish a trustworthy casino from a total scam. First off, if you’re new to all this, here’s the golden rule: **regulation is key**. If a casino doesn’t have a proper regulatory certificate (like from the Malta Gaming Authority or the UKGC), just run. No bonus is worth the risk of never seeing your funds again. Also — and I know no one wants to — read the T&Cs. That’s the only way to know what kind of wagering requirements they’ve slapped onto those so-called “juicy” bonuses.

Now, let me share a site I’ve been hooked on these last few weeks. It’s been a game-changer. The interface? Super clean. Payouts? Fast as hell. And the game selection? *Insane*. Slots, live dealers, blackjack, even some weird niche games I hadn’t tried before. Check it out here: <a href="https://rhythmgamingworld.com/forums/topic/gaming-app/">dragon tiger app</a> . What really stood out was the support team. I had a tiny issue with a bonus not working, and they got back to me in like no time. Compare that to other sites where you’re just left hanging — yeah, not worth it.

Also, if you’re into bonuses (and who isn’t?), this place offers some legit ones. But here’s the trick: don’t just go crazy over promos. It’s smarter to get fair terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and bet the farm — please don’t. But if you’ve got a little extra fun budget and you’re looking for a bit of online excitement, online casinos can totally deliver. Just keep your head on, control your bankroll, and don’t treat it like a side hustle. It’s for fun, not for a paycheck. Anyway, just wanted to drop my experience here in case anyone’s curious or trying to find a good place to play. If you’ve got your own stories or even some wild losses, I’m all ears — love talking shop about this stuff.

Good luck out there, and don’t let the house win too much ??

It’s no secret how President Donald Trump feels about sports teams turning away from Native American mascots. He’s repeatedly called for the return of the Washington Redskins and Cleveland Indians, claiming their recent rebrands were part of a “woke” agenda designed to erase history.

But one surprising team has really gotten the president’s attention: the Massapequa Chiefs.

The Long Island school district has refused to change its logo and name under a mandate from New York state banning schools from using team mascots appropriating Indigenous culture. Schools were given two years to rebrand, but Massapequa is the lone holdout, having missed the June 30 deadline to debut a new logo.
[url=https://kra-38---cc.ru]kra33[/url]
The district lost an initial lawsuit it filed against the state but now has the federal government on its side. In May, Trump’s Department of Education intervened on the district’s behalf, claiming the state’s mascot ban is itself discriminatory.

Massapequa’s Chiefs logo — an American Indian wearing a yellow feathered headdress — is expected to still be prominently displayed when the fall sports season kicks off soon, putting the quiet Long Island hamlet at the center of a political firestorm.
[url=https://kra-38--cc.ru]kra36[/url]
The district is now a key “battleground,” said Oliver Roberts, a Massapequa alum and the lawyer representing the school board in its fresh lawsuit against New York claiming that the ban is unconstitutional and discriminatory.

The Trump administration claims New York’s mascot ban violates Title VI of the Civil Rights Act of 1964, which prohibits recipients of federal funds from engaging in discriminatory behavior based on race, color or national origin — teeing up a potentially precedent-setting fight.

The intervention on behalf of Massapequa follows a pattern for a White House that has aggressively applied civil rights protections to police “reverse discrimination” and coerced schools and universities into policy concessions by withholding federal funds.

“Our goal is to assist nationally,” Roberts said. “It’s us putting forward our time and effort to try and assist with this national movement and push back against the woke bureaucrats trying to cancel our country’s history and tradition.”

Hey guys,

I mean, how do you even trust an online platform with your hard-earned money, right? But after digging deep (and trying out a few dodgy sites so you won’t have to), I figured out a few things that distinguish a trustworthy casino from a total scam. First off, if you’re new to all this, here’s the golden rule: **licenses matter**. If a casino doesn’t have a proper license (like from the Malta Gaming Authority or the UKGC), just run. No bonus is worth the gamble of never seeing your money again. Also — and I know no one wants to — check the terms. That’s the only way to know what kind of wagering requirements they’ve slapped onto those so-called “juicy” bonuses.

Now, let me share a site I’ve been playing on these last few weeks. It’s been a breath of fresh air. The interface? Super easy to navigate. Payouts? Quick — like 24 hours quick. And the game selection? *Massive*. Slots, live dealers, blackjack, even some unique stuff I hadn’t tried before.

Also, if you’re into bonuses (and who isn’t?), this place offers some legit ones. But here’s the trick: don’t just grab every shiny offer. It’s smarter to stick to reasonable terms than a huge bonus you’ll never be able to withdraw. I’m not saying you should go and blow your whole paycheck — please don’t. But if you’ve got a little extra fun budget and you’re looking for a fun way to unwind, online casinos can totally deliver. Just play smart, set a budget, and don’t treat it like a side hustle. It’s for fun, not for a paycheck. Anyway, just wanted to drop my experience here in case anyone’s looking for solid info or trying to find a decent place to play. If you’ve got your own go-to sites or even some casino nightmares, I’m all ears — love talking shop about this stuff.
