NSF Spool Hanger

thingiverse

I'm not sure what to make of this particular part, but it seems to get the job done adequately. This component is designed specifically for suspending standard 200mm, 7 3/4" spools (or smaller) from common NSF steel racks. There are two ways to utilize it effectively. Firstly, you can use one or two pins, three bearings, and two spool parts. The third bearing is inserted in the middle, while pin halves come in from each direction. Once I achieve the desired length, I add a tiny drop of super glue for extra security. Secondly, you can employ an 8mm or 5/16" bolt, two 608 bearings, and a coupling nut with a set of hangers. You can adjust these to any width or use a piece of all thread for multiple spools. I ensure that the bolts hit in the coupler and snug them together to prevent them from backing out over time. These components work remarkably well if you loop the filament through the rack, resulting in a very smooth operation. In the photo, I used honeycomb infill with no top or bottom layers in PLA.
