Instead, it’s an inquiry into how self-sufficient one can be with a FDM 3D printer. That didn’t stop him from torture testing the design to its limits as wheel bearings on an off-road go-cart.

Most 3D printers come with a pretty basic filament holder — often little more than a bar to hang the spool on. [Ivan Miranda]’s 3D printers run bigger spools than most, though, so he ha… ...

Hilube bushings (white) mounted in a 3D printer on a smooth guide rod. 3D Printers. The question of whether to use bearings or bushings seems to be more pronounced among those with RipRap printers.

This wild 3D printed card roller lets you do just that. Built by maker Paul Myers, the embosser ... You’ll also need some bearings to help the tubes roll but Myers is using skateboard bearings.

Embedded ball bearings bring balance to 3D-printed objects. ... but spare a thought for hobbyists who design and 3D print their own models, only to find they keep toppling over.
