Just a simple dust cover. I've read something about the dangers of static buildup in some plastic materials so be aware. I printed this in EasyABS from Fiberlogy Filaments using the generic ABS profile on the Bambu Lab X1C.
The author remixed this model.
I printed the nice dust cover by ultrajaxel (over at MakerWorld), but discovered that my game didn't fit because the extrusions on the inside were in the wrong location. I didn't know this, but I guess there is a difference in the cartridges for North America and the European ones. So I imported the model to Fusion and made some changes. Fitted very nicely afterwards.
