Spool Scale Roller

thingiverse

I built this as an easy way to measure what's left on a partially used spool. First, put an empty spool on the roller and set the zero weight. Then add the partially filled spool. This will show you exactly how much filament is still left on that partial spool. One of the first things I got frustrated with was not knowing if there was enough material to print through the night. I use a Dymo model P3 for my scale, which works well for this purpose. The bearings and weights I used came from Fidget Spinners, specifically 608 bearings. And again, it's worth noting that there are corrupted files in the images folder.
