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.

A ring found among the debris of Florida’s recent hurricanes awaits its owner
[url=https://kra17c.cc]kraken3yvbvzmhytnrnuhsy772i6dfobofu652e27f5hx6y5cpj7rgyd onion[/url]

Scattered across Florida’s hurricane-ravaged communities are piles of debris, remnants of what were once homes. Cherished memories — photo albums, family heirlooms, and tokens of love — swallowed by floodwaters and carried miles away, are now reduced to mere fragments and discarded amid the wreckage.

But in one of these piles of lost memories, a small, inconspicuous velvet black box was discovered with a ring and a note that read: “I was 18 when my parents gave it to me.”

Now, Joe Kovach, the engineer managing one of the debris sites in Tarpon Springs, Florida, where the box was found, is searching for its owner.

“Everyone has been basically dumping their entire lives onto the curb after the storm when everything flooded. My own boss’ house had 30 inches (of water) in it, and I saw his face and just how devastating it can be for everyone,” Kovach, an engineer with Pinellas County Public Works, told CNN.

“A lot of people in the community were really affected by these two storms, if there’s just a little bit I can do to give back, then that’s perfect.”

A contractor, who was gathering and condensing debris with an excavator, discovered the ring when he looked down and saw the box.

“This was a needle in a haystack for sure. For something like that to survive all that when everything else was so wet and saturated, that was kind of incredible,” Kovach said.
Although the ring was found after Hurricane Milton, Kovach is sure the treasure was initially lost amid the ruins of Hurricane Helene, based on the pile of debris it came from, which Pinellas County Public Works tracks. It is likely the owner of the ring is from Crystal Beach, Ozona, or Palm Harbor, Kovach said.

On Tuesday, after the contractor informed him about the ring, Kovach posted a photo of the box and the note on several local community Facebook pages, asking if it belonged to anyone. He did not include a photo or description of the ring to ensure it is returned to the rightful owner who can accurately describe it. On the inside lid of the box is a gold engraving with the jewelry brand, “The Danbury Mint.”

How a drab Soviet metropolis became Central Asia’s capital of cool
[url=https://omgto3.com]омг ссылка[/url]

Several cities around the globe have reinvented themselves in recent years, but none more successfully than Almaty.

Since the collapse of the USSR, Kazakhstan’s largest city (population 2.2 million and growing) has evolved from a drab, run-of-the-mill Soviet metropolis into the urban star of Central Asia.
https://omgto3.com
омг омг
Along the way, the city has developed one of the world’s most beautiful metro systems, grown into a thriving banking and finance center, complemented its vintage bazaars with luxury boutiques and modern shopping malls and reshaped its traditional gastronomy into a nouvelle cuisine that’s drawing raves from foodies around the world.

Almaty is also evolving into the cultural and artistic hub of Central Asia. It’s already got several world-class museums (including a “secret” underground collection that doesn’t even have a name) and a dazzling new cultural center slated to open early next year.

“It’s an incredibly livable city,” says long-time American resident Dennis Keen, a historic preservation advocate and founder of Walking Almaty.

“Green and clean. You don’t need a car. The public transit here is fantastic. And it’s very much the center of contemporary art and dining in Central Asia.”

Keen adds that whenever he tells someone back home that he lives in Kazakhstan, “Borat” inevitably comes up. The movie’s title character doesn’t paint a very flattering portrait of the Central Asian nation. But nowadays one is tempted to think that if Borat visited Almaty now, he would say, “Very nice!”

Why this small city is the ‘eyeglasses capital’ of Japan
[url=https://omgto3.com]омг[/url]
Japan is famed for its skilled artisans, masters who maintain a commitment to tradition while modernizing production techniques in line with the development of new materials and processes.

Many places in the country have grown famous by focusing on specific crafts, from exquisite kimonos to perfectly designed knives. Among them is the small city of Sabae, in Fukui prefecture, about a 3.5-hour train ride from Tokyo.
https://omgto3.com
omg даркнет
It’s widely known as Japan’s eyeglasses capital – and for good reason. Sabae produces over 90% of the frames manufactured in the country, according to the local government. Signs and objects shaped like eyeglasses can be found on city streets, and there’s even a museum and festival devoted to spectacles.
The art of making spectacles
Sabae, located on Japan’s main Honshu island near the city of Fukui, has been producing quality eyewear for more than a century.

It all started in 1905, when a local government official invited skilled eyeglasses artisans to come to the city to teach their craft, an attempt to create new opportunities for local farmers.

The move paid off. Today, Sabae has over 100 companies that collaborate to make pairs of glasses.

Though these studios use cutting-edge machinery to produce new frames made of metal and acetate, most stages still require the skilled hands and trained eyes of Sabae’s master artisans.

That includes Takeshi Yamae, a frame designer with Japanese brand Boston Club who has lived in the city for 17 years. He tells CNN one pair of glasses can involve more than 200 steps.

“I first design it, sketch it, then put it into my computer,” he says. “From the time I start designing, to the time I have the perfect product, it takes more than a year.”
