This is a remix of "MSX cartridge for FBlabs SD mapper V2" by Papipapito, for the Fractal 2000 SD Mapper
It makes mostly incremental updates:
- Stronger screw posts on the rear, these snapped off for me in other designs
- Rounded alignment posts for easier fit, some additional clearance, as these could snap off pretty easily
- Covered the LED indicators, but with a single layer, which depending on the filament, should be visible through when lit
- Two halves have a lip to mate against, with some clearance, instead of being flush
- Added grip surface to rear for easier removal of the cart
- Added MSX logo to the front, you can still affix a label though there's no affordance for one
- Rounded off corners for a more finished look
Use M2 screws, you may need to go up to M2.5 depending on the print.
You may need to use a brim to keep the corners from lifting.
