This is a model that created several years ago circa 2012, I originally made them from aluminium on my CNC. It's designed the repair a Garmin Edge cycling computer when the lugs designed to hold it to the mount break. It glues in place using epoxy 2 part glue. Do not use instant adhesive, you've been warned. My suggestion is to try resin printing it due to the fine details but maybe FDM with the right settings and material will work. Good luck
