Two size Spool Hub with 608 bearing by wigwag
by wigwagdevblog, published
After printout out my Prusa Handle and Spool Mount http://www.thingiverse.com/thing:28319 I decided to make my own spool hubs. I have two different spools, one from 3dprinterstuff from Amazon and one from Ultimachine. This spool hub fits both.
Step 1: Print two Hubs (you may want to mirror image one if arrows going backwards will drive you crazy)
Step 2: Snap in a 608 Bearing into each.
Step 3: Push fit into spool and add an axis, threaded rod or a number 2 pencil will work. I printed a 7.6mm diameter rod for it since I didn't want to cut rod and couldn't find a number 2 pencil.
Step 4: Place on Spool holder.
