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.

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.

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?
Thanks to [scat happens] for the tip.
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.

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.

3D printers are amazing things, but if one judges solely by the successes that get showcased online, it can look as through anything at all is possible. Yet in many ways, 3D printers are actually quite limited. Because success looks easy and no one showcases failure, people can end up with lopsided ideas of what is realistic. This isn’t surprising; behind every shining 3D print that pushes the boundaries of the technology, there are misprints and test pieces piled just out of sight.
If you have ever considered getting into 3D printing, or are wondering what kinds of expectations are realistic, read on because I am going to explain where objects come from, and how to recognize whether something is a good (or bad) fit for 3D printing. The important thing to understand is that printers have limitations, and to get a working idea of what those limitations are. The result will be a better understanding of what they can do, and what problems they can reliably solve.
3D Printers Have Limits
I recently had a talk with someone who wanted to know if a 3D printer could help with a problem they had. As I listened to them describe their needs, I realized I had in a way heard it all before many times.
My colleague actually had a fairly good idea of what printers could do, in theory. But they had very little grasp of what printers did not do, and that disconnect left them a bit adrift when it came to practical applications. To help address this gap, here are some tips that can give anyone a working understanding of the things 3D printers do not do well. Continue reading “3D Printering: The Things Printers (Don’t) Do”
There are more free 3D models online than one can shake a stick at, but what about paid models? Hosting models somewhere and putting a buy button in front of the download is certainly a solved problem, but after spending some time buying and printing a variety of non-free 3D models online, it’s clear that there are shortcomings in the current system.
What the problems are and how to address them depends a little on the different ways models get sold, but one thing is clear: poorly-designed 3D models are bad for consumers, and bad for the future of pay-to-download in general.
