TUSH spool holder with planetary gear

thingiverse

Well, I desperately needed a reliable spool holder for my 2 kg spool, but the shipment of ball bearings from China takes forever to arrive. So, I took k3xx's version of the spool holder and made some adjustments to make it print more smoothly on my Cetus 180x180 mm² bed by shortening the walls slightly. I also replaced the need for ball bearings and a bearing guide with a single bearing that uses emmett's planetary gear [1], which streamlined the design significantly. Additionally, I added a rim to the guide so it comes off the print bed in one piece, and a snap-in connection to the axes. Initially, this spool holder was meant to be a temporary solution until my ball bearings arrived, but it has been working amazingly well up to now, with almost no difference noticeable compared to traditional ball bearings. Both the axes and snap-in connection have also passed rigorous torture tests, so I might even consider using printed bearings instead of metal ones altogether. [1] Perhaps I should clean up the scad file and turn this into a separate project. ### TODO: These files are still rough and could use some tidying up, optimization, and modularization (just like the photos). I would really appreciate any feedback. Has anyone with longer-term experience used printed bearings in their 3D prints?
