30.5mm spindle spool holder, remixed from Ultimate 50mm.

New!
Added an adapter plug that fits the Makerbot type spools (around 53mm i.d.) to the spindle.

It's a filament spool spindle for the Replicator 2, remixed from thing 119016 with additional inspiration from thing 52838. I put a standard (7mm by 22mm diameter) skate bearing on this filament spool spindle. Thing 119016 gave me the spool holder base to start from; 52838 gave me the diameter of the smaller spool hole. The broad base is to prevent the large inset hole in one of my spools from allowing the spool to scrape against the Replicator's case. This thing rolls! I may make an adapter for 50mm spool and other sizes.
