2025 Pet Hacks Contest: A Barrel Of Fun For Your Dog

May 26, 2025 by Jenny List 3 Comments

If you ask someone for a piece of received opinion about Bernese mountain dogs, the chances are that the tale of their carrying barrels of brandy round their necks for the revival of those lost in the snow. It’s a story of uncertain provenance and may indeed be a myth, but that hasn’t stopped [Saren Tasciyan] 3D printing one for their faithful hound. In its own way it too is a saviour, for as well as a small camera, it carries a supply of dog poop bags.

It’s a two part print, held together with strong magnets. Waterproofing is achieved using liberal quantities of hot glue. There’s a protrusion on one side designed to take an action camera for a dog’s-eye-view of the world. The files are downloadable, so your pooch can have one too if you like. We are wondering whether a couple of miniatures of brandy might just fit in there as well.

It’s is part of the 2025 Pet Hacks contest, so if this has whetted your appetite, expect more. If your dog carries around something you’ve made, how about making it an entry of your own?

Keebin’ With Kristina: The One With The Part Picker

April 21, 2025 by Kristina Panos 4 Comments

If you do a lot of 3D computer work, I hear a Spacemouse is indispensable. So why not build a keyboard around it and make it a mouse-cropad?

That’s exactly what [DethKlawMiniatures] did with theirs. This baby is built with mild steel for the frame, along with some 3D-printed spacers and a pocket for the Spacemouse itself to live in.

Those switches are Kailh speed coppers, and they’re all wired up to a Seeed Xiao RP2040. [DethKlawMiniatures] says that making that lovely PCB by hand was a huge hassle, but impatience took over.

After a bit of use, [DethKlawMiniatures] says that the radial curve of the macro pad is nice, and the learning curve was okay. I think this baby looks fantastic, and I hope [DethKlawMiniatures] gets a lot of productivity out of it.

3D Model Subscriptions Are Coming, But Who’s Buying?

May 25, 2023 by Tom Nardi 51 Comments

We’ve all been there before — you need some 3D printable design that you figure must be common enough that somebody has already designed it, so you point your browser to Thingiverse or Printables, and in a few minutes you’ve got STL in hand and are ready to slice and print. If the design worked for you, perhaps you’ll go back and post an image of your print and leave a word of thanks to the designer.

Afterwards, you’ll probably never give that person a second thought for the rest of your life. Within a day or two, there’s a good chance you won’t even remember their username. It’s why most of the model sharing sites will present you with a list of your recently downloaded models when you want to upload a picture of your print, otherwise there’s a good chance you wouldn’t be able to find the thing.

Now if you really liked the model, you might go as far as following the designer. But even then, there would likely be some extenuating circumstances. After all, even the most expertly designed widget is still just a widget, and the chances of that person creating another one that you’d also happen to need seems exceedingly slim. Most of the interactions on these model sharing sites are like two ships passing in the night; it so happened that you and the creator had similar enough needs that you could both use the same printable object, but there’s no telling if you’ll ever cross paths with them again.

Which is why the recent announcements, dropped just hours from each other, that both Thangs and Printables would be rolling out paid subscription services seems so odd. Both sites claim that not only is there a demand for a service that would allow users to pay designers monthly for their designs, but that existing services such as Patreon are unable to meet the unique challenges involved.

Both sites say they have the solution, and can help creators turn their passion for 3D design into a regular revenue stream — as long as they get their piece of the action, that is.

Retrotechtacular: The Revolutionary Visual Effects Of King Kong

March 10, 2023 by Tom Nardi 13 Comments

Today, it’s easy to take realistic visual effects in film and TV for granted. Computer-generated imagery (CGI) has all but done away with the traditional camera tricks and miniatures used in decades past, and has become so commonplace in modern productions that there’s a good chance you’ve watched scenes without even realizing they were created partially, or sometimes even entirely, using digital tools.

But things were quite different when King Kong was released in 1933. In her recently released short documentary King Kong: The Practical Effects Wonder, Katie Keenan explains some the groundbreaking techniques used in the legendary film. At a time when audiences were only just becoming accustomed to experiencing sound in theaters, King Kong employed stop-motion animation, matte painting, rear projection, and even primitive robotics to bring the titular character to life in a realistic way.

Spool Tower: Empty Filament Spool Or Base For Miniature Civilizations

December 2, 2022 by Maya Posch 23 Comments

While churning through rolls of FDM filament, there are these empty spools that remain at the end. These can be thrown out with the trash, or be used as a standard base for miniatures, for use with Dungeons & Dragons tabletop gaming or similar, or just as a display piece. The latter is what the blokes over at Digital Taxidermy ran with when they started their first Spool Tower Kickstarter campaign. Now they’re back with Spool Tower 2: The Re-Spoolening.

These are STL bundle packs that should contain all that’s needed to turn an empty filament spool into an art piece, minus of course the painting. To get a free taste of what the experience is like, Digital Taxidermy provides a few free STLs, such as for the Ye Olde Taxidermee Shoppee and the Hab Block from the new crowdfunding campaign.

This effort raises the interesting question of what other standard (plastic) shapes of packaging could conceivably be used in a similar manner. After all, why print the whole thing when half the model could be made from something you’d otherwise just toss into the trash bin?

3D Printering: Today’s Resins Can Meet Your Needs

June 13, 2022 by Donald Papp 27 Comments

Filament-based 3D printers spent a long time at the developmental forefront for hobbyists, but resin-based printers have absolutely done a lot of catching up, and so have the resins they use. It used to be broadly true that resin prints looked great but were brittle, but that’s really not the case anymore.

A bigger variety of resins and properties are available to hobbyists than ever before, so if that’s what’s been keeping you away, it’s maybe time for another look. There are tough resins, there are stiff resins, there are heat-resistant resins, and more. Some make casting easy, and some are even flexible. If your part or application needs a particular property, there is probably a resin for it out there.

Baby C-17 Sends Imaginations Soaring

June 6, 2021 by Roger Cheng 17 Comments

The C-17 Globemaster III is a military cargo jet that can carry what their commercial counterparts can’t, to places those other planes can’t go. The people who keep these planes flying are proud of their capable airlifter, but it’s hard to show them off. Solution: build a scaled-down version more suitable for driving off base for a parade down Main Street and other community events.

While the real thing was built under an expensive and contentious military procurement process, the miniature was built with volunteer labor using castoff materials. The volunteer force included maintenance crew whose job is to know the C-17 inside and out. Combined with fabrication skills that comes with the job, the impressive baby plane faithfully copied many curvatures and details from full-sized originals. (Albeit with some alteration for its cartoony proportions.) Underneath are mechanicals from a retired John Deere Gator utility vehicle. They usually resemble a large golf cart except with a cargo bed and more rugged suspension. Basically they are to golf carts as a C-17 is to a 767. Amusingly, the little plane has its own rear loading ramp, superficially preserving the cargo-carrying capacity of the original Gator chassis.

Interior features continue, though the official picture gallery doesn’t show them. There is a flight deck with control panels and various sights and sounds to keep visitors entertained. Enough details were poured into the exhibit that some people had to ask if the little plane can fly, and the answer is a very definite no. The wings, and the engine pods mounted to them, are only for show carrying The Spirit of Hope, Liberty & Freedom. It is quite a long official name for such a short stubby thing.

We always love to admire impressively put-together miniatures, and not all projects require skill of aircraft mechanics. Like this very approachable miniature forklift project. But there are plenty of other projects whose skills put us in awe, like this remote-control car powered by a miniature V-10 engine.
