A pair of Printrbot Spool Plug designed to keep your filament spinning and you lazy.


I got tired of running to the printer every 10 minutes to readjust the length - Since I live in Europe I can't just order a Power Tower so I decided to roll my own.

2x 608 bearings - the same the Printrbot uses
1x 8mm rod - smooth is best, i use a hollow aluminium rod cut to size

1x cradle - Make sure you have a plan for the base station that will hold this setup, it needs to be cradled somehow. See picture for reference.


PRINT WITH SUPPORT: rectilinear 2mm and remember to sand the support down completely!

Also I strongly recommend adding the bearings while the prints are hot. Once the prints cool the plastic contracts and will grip the bearings.

Also note that i repositioned the holes after making it since one of them was offset wrong. I hope the holes are better now, please give feedback. As soon as one does I'll fix/mark it out of WiP.

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/4Ehi5KXpIIC
