while i have printed and used many that were just fine they always had a bit too much wiggle room for the spool to move. while they did still work i wanted to design something better. so here is my attempt at such a spool holder. requires 8 608 roller blade bearings. they are held at 45 degrees off center, which puts the two of them at a 90 degree angle from each other. this allows for even contact with the edges of the spool. think of it as auto alignment of the spool to the bearings. must print 2 obviously.
