The ultimate spool holder
by skibbe10, published
This is a simple, yet powerfull, spool holder for the Makerbot Replicator 2.
It is designed to just clip-on on top of the printer, under the lip of the "roof".
The 3 rods is 12mm brass tubing, which slides into the holes of the feet and top hooks. No fastening needed. The crossbar is press fitted in the hooks. The standing rods are have a 20degree angle backwards for stability. Mounted with the hooks forward to have the center of gravity above the mounting position.
The spool bearing adapters are made in two halfs, bolted together with 3mm bolts. The adapters are designed to hold spools with inner diameter 52 up to 56mm on one side, and 32mm if you turn them(Pic 5&6). If you make 3 spool adapter sets, they can hold both a 32mm and 52-56mm spool.
My adapters warped a bit under printing, so thy have a perfect pressfit with the spools.
