Gizmo Watch 3 Band Adapter 20mm for Elastic bands

Daughter kept breaking the plastic piece to connect her elastic bands to her Gizmo Watch 3.  I found another model but it didn't have the proper attachment piece to fit the band. Model is a bit rough and could use some modifications to make it a little nicer. Next time it breaks I will be updating the model to be smoother and maybe create it in Auto cad from scratch now that I have the measurements. 

I printed it on my Geeetech M1 with a 0.2mm nozzle with 0.04mm line height, using Bambu lab pla Hot Pink. This should probably be printed in something stronger the pla.

Supports on Auto Tree, with support critical regions only. 

4 walls and 15% cross hatch infill. 

7 top layers and 5 bottom layers

I used the pin from the broken part, but the ones listed on amazon should also work, but I have not tested them.

Simply slide pin into the hole and push the other side through the loop of the elastic band. I made it tight so my daughter can't easily remove it.
