SNES:3D Printed Cart Slot

It is possible to make an SNES take Super Famicom cartridges, which it is normally not able to due to some tabs in the cartridge slot, using 3D printed parts.

Printing The Parts

You can get the files to print the part, uploaded by SyskoRodriguez, from thingiverse.

It is recommended to print the 2 main components separately (cartridge well and power sliders plate), as printing the whole part at once will require a lot more supports.

Here is an example layout of the parts on a print bed. With this layout, the sliders part does not need any supports and the well part uses automatically painted-on supports. Using this orientation for the well makes it easier to remove the supports and install the part than if the orientation were flipped vertically.

Assembly

First off, you'll need to disassemble your SNES and get the top shell piece off. This can be done by unscrewing the 6 gamebit screws on the bottom of the console, flipping it over, and lifting the top off.

You should see the underside of the top cover, like this.

Remove the highlighted screws and remove the reset slider spring with some tweezers by pulling the lower spring hook down towards the bottom of the shell and it should come off easily.

You should then be able to lift the cart well off the shell top.

You then want to remove the white reset slider piece from the original cart slot and insert it into the 3D printed part.

Finally, place the 3D printed parts in the top shell and screw them on and attach the top shell back onto the rest of the console, essentially reversing the disassembly step.

And that's it! You can now insert SFC carts into your SNES. (Note: if you have an NTSC SNES, unless you have a hardware region-free mod installed you can only play NTSC SFC carts, such as the Japanese ones.)
