This is a little scale model of an NES cartridge to go with my Raspberry Pi mini NES replica.
The main case files are here.
A user named stefanli made cartridge sleeves that fit these little carts.
The included supports can be used instead of slicer supports. I got better results this way.
The pins locate the two halves together and I used super glue to bond them.
The label was printed on thick paper with clear packing tape applied to give a glossy finish.
