This is a fully re-modeled build of a MicroSD case inspired by Kozalakis's one on Thingiverse, borrowing some ideas from Kroki's remix of it.
This version relies on fairly close tolerances, so it may be a bit temperamental on some 3D printers (Details below).
The main differences from the other two:
The model is intended to be printed with the notched “connector end” of the case down. The print should not need any supports as all overhangs are either short (i.e. inside the MicroSD slots) or gradually sloping (the inside-top of the box).
I added a second version that has added 0.2mm thick “frog toe” sprues on the outer corners of the base. These may assist with bed adhesion and preventing curling during the print. The sprues are more easily removable than a conventional brim addition.
This was all done using a free OnShape account and the model source is here.
The author marked this model as their own original creation.
