Based on Benjamin Ander's wall shelf design (Which is based on Moiras_creations), I wanted to fit some 10mm magnets in these at some different sizes.
For each model I made a 1500x and 3000x scaled from original size.
File names are in Length x Width x Height in millimeters.
If you want it to fit a different magnet size, or want a specific model a bit larger, just let me know; I have the files all up.
Fits:
10x2mm magnets → You can buy a multi-pack of magnets for under $15 which is what I use for most of my crafts.
Glow in the dark looks particularly fantastic.
