Filament Spool Roller Small half roll - Snap Fit 6x19x6mm Bearings 626zz

I got a 1lb or half spool of nylon filament and it's a good candidate for a sealed box. The normal size spool rollers were too big so I made this half size roller that utilizes 626 bearings that I happen to have a bunch of. Print 4 each of the side and foot to make a filament roller pair. The 626 bearings have a 6mm hole and are 6mm wide by 19mm outside diameter (size of a penny).
