RailCore Internal Spool Holder

thingiverse

This is a revised version of my original spool holder design that allows for mounting filament spools inside the printer enclosure. It fits all major brands, including atomic spools, and provides full Z travel so the bed doesn't hit the spool when mounted on the inside back panel. Find a suitable spot to drill a 1/4-inch hole for the mounting bolt. To assemble it, you'll need some additional hardware: - (1) 1/4-20 x 2-inch bolt - (1) 1/4-20 nylon lock nut - (2) 1/4-1-inch washers Place one washer on the outside of the panel, then screw in the bolt to go through to the inside. Put the holder over the bolt, add another washer inside the hollow area, and secure it with the lock nut.
