This is a roller style spool holder that will mount onto a 2020 extrusion. I have 3 versions just because I kept getting another idea to try out.
I've also included a bearing fitter/remover for those stuck on bearings. Just fit it over the rod and hammer the rod or bearing on/off.
V1. Simple roller on a rod. No bearings required. (no pic)
V2. Barrel roller with bearing ends. The bearings are fitted inside the length of the roller. (1st pic)
V3. Thin rod with bearings at both ends. This is the longest one as it requires clearance for the bearings outside the roller length. The base is also longer. (2nd pic)
The spool slides over the plastic pretty easily. I don't think bearings are required but it may help if the spool is made of other materials like cardboard.
*Update 5/24/2017 - Added rod holders with a tighter fitting in case the originals are loose.
