Remix of the original keychain model (https://makerworld.com/en/models/68130#profileId-79094):

Makes for great wall art, coaster, magnet.

• Removed keychain ring
• Fits two 8x2mm magnets
• Scaled up a bit

If you don't have two 8x2mm magnets, you can edit the size of the magnet holes in Bambu Studio by adjusting the size of the negative cylinder (Process → Objects → Scale). Or you can just use superglue to attach the magnets directly to the back of the model.
