Railcore II 300ZL Internal Spool Holder

UPDATE: The V3 is a larger diameter holder and it will hold the Atomic spools. If you do not use wider spools the V1 is better to use as it gives you more clearance from the bed.

This spool holder mounts inside the 300ZL on the back panel. It allows majority of spool sizes to fit without causing clearance issues with the bed including the Atomic spools. Included in the files is the spool holder itself, a drill jig to drill the 4 holes to mount it and the filament tube guide.
