As a retro gaming fan I love my MiSTer FPGA, so I designed a keychain based on its mascot MiSTer Kun. The Logo was originally designed by baxysquare and I used the files from his github page. Thanks a lot.
Print it in multiple colors by adding print stops where needed (in .3mf already added).
Have fun and happy printing.
The author remixed this model.
Added a hole for a keyring.
