A 3D-printable NES cleaning cartridge modeled after the official one included with the cleaning kit. It's been optimized to be better for 3D-printing however. You'll need to wrap the card with a thin piece of cloth as obviously cloth is something that can't yet be 3D-printed. lol
Usage instructions as per the original manual:
Printing tips:
The top piece should be printed upright with supports under the handle and under the tabs as shown here below. I also recommend using a raft as there isn't much surface area on the bed.
The bottom piece just needs supports under the hole on the right as shown below.
The author marked this model as their own original creation.
