Hook and Loop Coupler

thingiverse

I created a new version of this coupler, remixing the loop part and designing the hoop, pin, and spring. It works amazingly on my Christmas tree train, using a #4 1/2" length screw. I also designed a hook that is 2mm longer, which should work better on R1 turns.

How I Designed This: TinkerCad was my design tool of choice.
