Magnetic Slip Clutch for movie reels (6mm D-shaft to 8mm square shaft)

cults3d

This is a magnetic slip clutch for mounting a 16mm film reel to a motor. The input side accepts a 6mm D-profile shaft and the output side features an 8mm square shaft for mounting the reel. In addition to the printed parts, you'll need 1 x washer (I measured around USS 1/4" dimensions, but you can use a drill to remove the inner bump and place an SAE 1/4" instead) 3 x Neodymium Ring Magnets (Magnet Source brand, sold at home depot, 9.53 mm OD and 1.53 mm thick) 1 x 1/4"-20 x 2" set screw Also a tap and tap wrench for 1/4"-20 threads will be handy, and your choice of adhesive. I used a hot glue gun but super glue would probably be easier.
