MP Select Mini Small Diameter Spool Arm

thingiverse

I designed this spool arm specifically for smaller diameter filament spools like Dremel PLA. It fits perfectly into the slot on my Monoprice Select Mini, just like the default arm that comes with it. This was one of my first DIY projects, and though I'm not a pro, I think it's functional enough. I've put it to the test, trying to bend and break it by hand - it holds up strong. Plus, it can hold a spool at angles beyond 45 degrees. If you're looking for a solution for smaller diameter spools, this might be just what you need.
