This is a fully re-modeled build of a MicroSD case inspired by Kozalakis's one, borrowing some ideas from Kroki's remix of it. I didn't actually use any of their source, rather building from scratch using SD/MicroSD card dimensions.

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 case holds 10 MicroSD cards (2 x 5)
• There are registration tabs in the slots, so the SD adapter lid should only go in with the label side out and the connectors on the inside of the box.
• The SD adapter should register with the card retention tab on the inside of the slot (The original design used the write-protect tab slot to register the card). Depending on the material used and tolerances, this may be tight or wear out after a while.
• The SD adapter can be pushed-out from the connector end (the main reason for Kroki's remix).

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 and use less material too.

This was all done using a free OnShape account and the model source is here

The "Frog toes" version has sprues that perform the function of a brim, but are easier to remove and use less material.
