Clip on spool holder to fit 1" diameter wire shelving post. Hook is 2.50" long to hold 1kg filament spool. Can also be used as a coat hook. To install, clip hook around post and slide up / down into position until ribs on hook clicks into indents of post and then slide retainer clip to secure in place. I have been able to load hooks with over 25 lbs of weight. Best printed in PETG.

This is a remix of my original design that can be found here:
