RepBox rollers

thingiverse

I found the TUSH style spool rollers in the RepBox to be a bit fidgety. While holding a spool and trying to slide them to align, I was always knocking them over. Since I never have more than 5 spools in the box at a time, and the vast majority of my spools are all under 3.5" wide, I decided to make a bunch of individual spool rollers that run the entire length of the box. This allows me to just drop a spool onto one of the 5 sets, no alignment needed. The rollers use the original bearings. Bearings should press in, I used a threaded rod with some washers and nuts to press the bearings in, they were tight. You'll need to print 20 of the Roller-ends, and 10 of the Rollers. I've included the Fusion files in case someone wants to enhance the design, or needs to tweak the clearances for their box. Updated 8/12/2019 - Someone wanted a variation of the roller-ends that could lay flat on a surface, so now there is one. You'll need to use adhesive tape to hold these in place unless you have another enclosure to hold things from moving about. I have no plans to create a full base, as there are many such spool holders on Thingiverse already.
