Parametric horizontal spool holder (DIY bearing)

thingiverse

Horizontal spool holder for Anet A8. If mounting on the top like I did you may need to shave off a small section of the frame so the spool doesn't rub. I haven't tried printing with it yet but it does spin nice and smooth. I expect I will need to make a filament guide to ensure the filament does not slip off the side of the spool. EDIT: It works excellently and I made a simple [filament guide](https://www.thingiverse.com/thing:2514784) compliment this spool holder. The stl files are optimised for rigid ink filament with a 54mm inner diameter, but the scad file is attached for anyone to make their own version. I wanted to make a holder which would fit in the reasonably confined space where I keep my machine and I didn't want to wait for bearing so I used some steel balls I had laying around. These are 12.5mm balls like those found in sets of geomag. You will need 16 balls in total. 13 for the base and 3 for the top.
