The default laser-cut spool holder for the DeltaPrintr didn't fit some of my smaller spools, so I made this one which can accommodate anything with at least a 33mm Diameter hole in the center. It slides in exactly the same way the old one did and uses the circular base plate from the original. I had a little trouble with a few of the tolerances, but I think this model should work. If you have any problems or requests, please let me know.
