Printrbot Filament Spool Guide Adaper

thingiverse

Designed to work with Walpeup's Low Profile Ball-Bearing Printrbot Simple Metal Spool Holder (https://www.thingiverse.com/thing:2036443) I have the Z-axis upgrade for the Printrbot, and my old spool holder sat vertically atop the printer, making it awfully top heavy. So I loved the idea of a horizontal spool holder to lower the center of gravity a bit. I printed one of Walpeup's out, but unfortunately it didn't work with most of the spools I have from different filament companies. The central hub (the guide piece) it too big for some of my spools. The vertically oriented bearings also don't always align with a smooth surface on my spools. So I designed this simple part to replace the original guide. The upper cylinder is small enough to fit inside all my current spools. I added a thin flat disc attached to the bottom of the guide piece for the bearings to roll against and ensure smooth operation across many spool types. You will need to print the SpoolBase part from Walpeup's thing page (https://www.thingiverse.com/thing:2036443). I posted the OpenSCAD model, and it would be super easy to adjust if this guide does not quite fit your own spools.
