T-Slot Filament Spool holder M8 and American Standard Size

thingiverse

This spool holder will let you use larger spools in addition to smaller spools. Our local stores don't stock M8 threaded rods, so I decided to support common American-size threaded rods and nuts in addition to Metric. Required hardware: Dual Setup: (see picture) 1x 3/8 threaded rod, 10 inch 8x 9/16 nuts 6x 3/8 washers 4x Spool_caps 1x Spool_holder_body 1x feed_tube_spinner 1x feeder *for M8 setup, replace all hardware with M8 nuts, washers, and rods! *Study Fig. 1! The "Jam Nuts" prevent the inner caps from moving, while the "Adjusting Nuts" tighten the spools. You need your spools loose so they can rotate freely. When adjusted properly, the "Jam Nuts" will prevent your spools from being over tighten. No nut required on spool holder body in a dual spool setup, which makes servicing both spools by removing either cap.
