NSF Spool Hanger

This is a pretty specific part but it serves it's purpose well enough for me.

This is for hanging standard 200mm, 7 3/4" spools (or smaller) from the common NSF steel racks. Two ways to use this.

1-2 pins, 3 bearings, two spool parts. The 3rd bearing goes in the middle, pin halves come in from each direction. When I get the length right I add a tiny drop of super glue.

2-A bolt (8mm or 5/16") 2 608 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. I make sure the bolts hit in the coupler and snug them together to prevent them from backing out over time.

These work really really well is you loop the filament through the rack, very smooth this way.

In the picture I used honeycomb infill with no top or bottom layers in PLA.
