8-Track respooler on RepRack spool holder

Drop in replacement for one of the rollers on the “Auto-Rewind Spool Holder for RepRack” (found here ). Allows mounting respooler from the 8-Track project (which is smaller version of Filamentalist). Though in order to actually use it on a RepRack you need to use the original frame and tensioner ( here ). The new one unfortunately interferes with the pipe of the RepRack. BOM In addition to parts needed for the original rewinder and for the 8-track respooler, you'll need the following for this sled: 4x M3 Heat set inserts (5mm OD x 4mm L) 4x M3x6-8mm Countersunk screws
