I like the idea of Game Boy carts (Game Pak is Nintendo’s old name for a cartridge) on display looking like they’re standing up by themselves. Partly that was for photos, but mostly I just like how it looks. Every stand out there ruined it. They tend to have a big base and a big lip, so you end up looking at the stand. This one is a sliver of plastic that props a cart at 15 degrees and mostly disappears behind it. It turned out collectors wanted that for their shelves too.
Two versions
One STL each (that’s the file you load into your printer’s software): one for Game Boy and Game Boy Color carts, one for Game Boy Advance. The cart sits in a shallow channel and leans back. The foot has a hole through the center so you can screw it to a shelf if it’s going somewhere it might get bumped, but it stands on its own fine.
Print a row of them
- 0.2 mm layers, 2 walls, 15% infill
- 26 minutes
- No supports, no raft, so there’s nothing extra to peel or clean off afterward
- Any material. PLA and PETG are both common printing plastics, and a clear low-density print of either makes it even harder to see behind clear carts, which one remixer pointed out and is right about
If yours snaps right off the bed, your filament is wet. Filament pulls moisture out of the air and prints brittle, and thin parts don’t forgive that.
The remix thing
On MakerWorld, a remix is a version of somebody else’s model, posted with credit back to the original. In May 2025 another designer uploaded a near copy with small changes and no remix credit, which is against both the license and MakerWorld’s rules. They took it down, we talked in the comments, and I told them their version had actually improved the strength of mine and they should relist it as a proper remix. They said mine fit a little tight on their printer, and theirs was built solid.
