Half Rivet for Adult Mary Jane Croc

I wanted to have a back strap for the adult Mary Jane Crocs so I made this longer half rivet piece in SolidWorks.

I printed this at 0.12mm layer height in PETG. Print straight up and down. Supports not necessary.

Original Croc rivet button = mushroom looking one
Half rivet button = Sorry piece looking one

Step 1: Take off strap
Step 2: Take off Croc rivet button
Step 3: Take apart Croc rivet button
Step 4: Put printed half rivet in Croc
Step 5: Put strap over printed half rivet
Step 6: Put on original strap
Step 7: Put on original Croc rivet button
