Filament Holder Remix with 2 pluggable shafts

thingiverse

I created a remix based on the "Filament Spool Holder" by HugoHuge (https://www.thingiverse.com/thing:3020026), as well as mjoaris' and Keleo's remixes (https://www.thingiverse.com/thing:3209211, https://www.thingiverse.com/thing:3222112). I studied HugoHuge's design but opted to print mjoaris' version because all my filament spools fit perfectly in this shortened version. I encountered the same issue as mjoaris with the small shaft breaking off from the roller. I then printed the roller with a removable shaft, inspired by Keleo's design, but found that I couldn't fit the roller into the housing with my 608z bearings attached. To resolve this problem, I shortened the "shell" by 1 mm and made both shafts pluggable. This should make it easy to print without supports. Before you ask, I didn't intentionally leave the shafts imperfectly round. I used Inventor to design them, but it seems the software couldn't save them in a perfectly round shape. Luckily, this issue didn't affect the functionality of the spool holder.
