3D filament roller stand

Two parts design (2X each). The ball bearing is 4X standard 62-30-16mm steel ball bearing. Be aware that the parts have somewhat fine tolerance and I heated the ball bearing in the oven to 50-60 C degrees before I pushed them into the drum part. Could be some sanding is required to remove print artifacts.Just in case you wonder big bearings - just to make it heavy and stable on the table.Update: Added a base Plate and 4 pads to join the parts. Not tested but I hope it will work for you. I also made a TPU pad with a hole for a M4 screw just in case the snap feature is not strong enough.
