Ryobi HT20VSK holder clamp

prusaprinters

This holder is designed for the Ryobi model HT20VSK, which has an oval body shape, approximately 46mm x 43mm in the clamp area. The front mount is slightly tapered inside to allow the motor to just be slipped into the front mount until snug, and then close the rear clamp.  The front holder ID is sized for the motor's bare threaded front end (approx 21mm). I printed this in ASA at 0.2mm with 4 perimeter walls, 5 and 4 top and bottom layers, respectively, and 30% gyroid infill.  You may need some supports depending on how you face the parts to the bed.  The screw holes are sized loose on the outer tangs and snug on the inner barrel, so that you just thread them in and no nuts required. You will need two M3x12mm flat head screws and one M3x20mm flat head screw. Also included is a fully parameterized Fusion 360 model for the design.  The latch design is imported/referenced by the holder  model.I borrowed ideas, such as the latch design, from Vegster's Dremel holder latched MK2 (but not nearly as sexy).  https://www.printables.com/model/42146-dremel-3000-latched-holder-mk2
