Anyone with a desktop 3D printer knows that it can be a bit nerve-wracking to leave the machine alone for any extended period of time. Unfortunately, it’s often unavoidable given how long more complicated prints can take. With big prints easily stretching beyond the 20 hour mark, at some point you’re going to need to […]
If you want to make serious assemblies out of 3D printed parts, you’ll eventually need to deal with threading. The easiest way is to make a nut trap that you can either insert a standard nut into after printing or even during printing. However, there are limitations to this method. If you want a real […]
The Volkswagen Beetle, and yes the bus and the sexiest car ever made, are cars meant for the people. You can pull the engine out with a strong friend, and you can fix anything in an old Volkswagen. VW realized this, because in the 1950s and ’60s, they came up with plans for tools designed […]
Combination locks! They’re great if you’re skilled at remembering arbitrary strings of numbers, and have a dramatic flair that’s made them a famous part of many a heist movie. They come in a wide variety of styles, and are vulnerable to a different set of attacks than the more typical pin-tumbler locks used on a […]
Last year, mathematician and professional optical illusionist [Kokichi Sugihara] came up with an arrow that only points one way. Technically, it’s ‘anomalous mirror symmetry’, but if you print this arrow and look at it juuuussst right, it appears this arrow only points one way. [Ali] had the idea to turn this arrow illusion into something […]
Inspiration runs on its own schedule: great ideas don’t always arrive in a timely manner. Such was the case with [Daren Schwenke]’s notion for creating a 3D-printed blooming rose for his valentine, a plan which came about on February 13. Inspired by [Jiří Praus]’s animated wireframe tulip, [Daren] figured he could make a rose from […]
When you really start fine-tuning your 3D printer, you might start to notice that even the smallest things can have a noticeable impact on your prints. An open window can cause enough of a draft to make your print peel up from the bed, and the slightly askew diameter of that bargain basement filament can […]
We often think of 3D printing as a way to create specific components in our builds, everything from some hard-to-find little sprocket to a custom enclosure. More and more of the projects that grace the pages of Hackaday utilize at least a few 3D printed parts, even if the overall build itself is not something […]
Hackers and makers see the desktop 3D printer as something close to a dream come true, a device that enables automated small-scale manufacturing for a few hundred dollars. But it’s not unreasonable to say that most of us are idealists; we see the rise of 3D printing as a positive development because we have positive […]
OpenSCAD is one of the most powerful 3d modeling applications around. Its beauty is in its simplicity; if you need a box, you can just write the code for a box. If you need some bit of plastic to keep your 3D printer running, you can just write the code for that bit of plastic. […]
