Rack taillight adapter for mudguard (customizable)

I designed this adapter to fit my taillight from bicycle rack to fit in mudguard place, where only one screw holds taillight.

Enjoy the design, on Salsa Fargo this turned out very tight, but I wanted to make it flat, so it would be as strong as possible, to prevent layer adhesion issues.

I printed this model out of PET-G, I used high infill and low fan speeds to increase strength of the adapter.
