3030 Spool holder (Hypercube Evolution)

thingiverse

This is a streamlined version of thing 3155344 that eliminates ball bearings altogether. It works better for me because it gets rid of the spool 'runaway' caused by the very low friction of the bearings. Included are both STL and Fusion 360 design files. If you want to change the holder's length, simply adjust the net_length user parameter in the Fusion 360 design. I used the STL model on the left side of the printer but it should work just as well on either side. To make the support wall visible or invisible from the front, all you have to do is mirror the model in your slicer. I printed it with PETG for its lower friction than PLA. Layer height was 0.2mm, infill was 25%, and no material support was used (just rotate it in your slicer to lay on the support wall).
