Remixed the top bit of the Multisystem 2 Analogue to allow for front loading of NFC cards rather than back loading because it wasn't an ideal solution for me. Haven't tested sliding in an NFC card while there's an expansion cartridge inserted since I don't own any, but you might be able to do it.
Prints top side down, with no supports. For reference, took roughly 40 minutes on my Bambu P1S.
The MMS2 logo, cartridge cover and springs in the NFC card slot from the original should just swap over.
The author remixed this model.
Modified the back NFC card slot to allow for sliding in nfc cards from the front rather than the back.
