Rubbermaid Fast Track garage hanging hooks and clips for hanging tools and other things in the garage. Currently on my "rev 1.3" design - if anyone needs/wants any additional designs or configurations, let me know.
I was shooting to keep any configuration/hook under roughly 50% cost in filament compared to the hooks purchased at the local home improvement store - if the filament cost got too high, why not just buy the $8 hooks?
Clips print on their flat side on the bed.

3/4 of a 1kg spool later, I'm pretty happy with the progression so far.
These hooks have been designed to use an upper clip and lower hook, being assembled together with a 2" long 1/4" bolt for maximum flexibility. Printing in two halves allows more flexible construction and replacement of broken pieces while also allowing the pieces to be printed without needing any supports. Bolt sinks into the clip that attaches to the fasttrack rail has geometry to hold the head in place.
All designs were printed and tested with 3 perimeters and 25% infill. Printing with 2 perimeters results in inconsistent hooks where printing the same hook will get dramatically different weight limits. Printing with 4 perimeters results in a stronger part that will hold up better over time, as does changing infill type/density.
All parts were printed and tested to meet or exceed 200% of their weight rating via a static hanging test without failure and at 100% of their rating the tip of the hook did not drop more than 10% of the hook's functional diameter.
Using superglue does not significantly add strength to the part, as the bolt provides the vertical weight support, just don't over-tighten the nut.
