Retro Cartridge Game Holders for Nintendo Switch - NES Style
It comes in two different sizes, the small size holds up to 6 games, the standard size (close to orginal size) holds up to 12 Switch games.

It‘s also easy to print and only needs few supports on the small cutout at the top.

Here are the dimensions (mm):
Small: 100x88x16
Standard: 140x120x20
Please note that you`ll need the doubled width of printing space as this will be printed in place folded up!

The whole thing is printed in place so no need to assemble anything!
You need to put a stop in your slicer to embed four 8mm x 3mm magnets (care to put them in the right way!). The magnets can ne found cheaply on amazon or aliexpress.

If you sell these on etsy these will probably pay off within a few days and sells!
