Ender 3 Ball Bearing Filament Roller Easy Print + Source

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3732566.

Remix of HugoHuge and mjoaris's Filament Holders to be easier to print, compatible with smaller spool diameters, and capture the required 608 bearings so the roller doesn't fall out.

Best printed at above 20% infill and 3 or more perimeters/walls.

I got rid of the majority of support requirements aside from the threaded end and the nut threads; just use tree supports or lines so they break away easy.

I was a bit worried over removing half of the holder material from the previous design so I ran a stress simulation on the part and all seems well. Results in the photos.

Let me know if there are any design changes that would be more effective, or any other fitment issues you may run into. Printed this myself at 100% but I have my printer pretty dialed in I think.

Note: I created a fitment test for the roller plug, so just print the "Filler Roller EZ Print Fitment Test" and one each of the "Filler Roller Plug EZ Print" and 0.1-0.3mm undersized versions to check which has the best fitment. Or just print the original file with additional supports.

EDIT: I'm not sure how to reorient the objects for best printing in my CAD program (Inventor) any insight would be helpful.
