CR10S/Adimlab 20x20mm frame quick change filament holder

This was designed so that I can use multiple manufacturer's filaments knowing there are many different sizes of spools. The filament rolls freely without being hindered by a static arm. It is smooth and slimline, and the filament should not fall off in case of a filament tangle. I designed this in Fusion360 for my ADIMLab gantry printer. It will fit any printer that uses 20x20 framing material. I had a few bearings from the shop so that's what I built, using an R16-2RS or similar sized bearing. I would change the position of printing to be different than the thing file pics show. I printed this using PLA at a relatively fast speed (80ms). If you want it to be without any artifacts, you will need to slow it down a bit. I used old school model glue to fuse the plastics together. It works great, but you could use plastic epoxy or whatever works for you. Not too much or you will mess up the bearing. Make sure you let the glue dry in between operations so it's solid. 1) Insert the plug into the bearing (no glue needed). You may have to trim/bevel the edge a bit to get it into the bearing. It's a snug fit. 2) Insert the spindle into the plug after adding a little glue. 3) Insert the spindle assembly into the upright's body. 4) While making sure the bearing is all the way to the end, add a little glue to the outside of the ring and push the ring into the body making sure it is TIGHT against the bearing. I didn't use the holes to fasten the holder - it's solid all by itself. This thing is fantastic. I hope you enjoy!
