Uni-T UT33 Case Insert

I couldn't find the proper part from Uni-T for my multimeter, despite it having a slot in the case for something. So I designed this part. Due to the size, it needs something like a 15mm wide strap which is actually a bit difficult ot find. If I made it any bigger ,though, it would not fit through the slots in the rubber case of the multimeter. Next up, a magnetic disc with voids to hold neodynium magnets, similar to the Fluke magnetic strap. I used PLA and so far it's held up. Would probably be best to use something stronger though.
