Spool roller

A simple redesign of ianlee74's roller.

Modified dimensions to fit my spools, and added some bearing edge stops on the inside, so the bearings can be pressed in, but remain flush with the outside surface.

This roller is to be placed inside the filament spool, to use in combination with a spool holder that uses an 8mm rod, I used my "Spool Skeleton Mount for Delta Kossel" http://www.thingiverse.com/thing:1740925 with an 8mm threaded rod and 2 x M8 wing nuts.


Dimensions: 31 x 31 x 105mm
