I can print/cut to pretty much any standard sized cube though if you need special dimensions

I've never tried designing a cube sticker set so I decided that the most sensible next step was to pull the stickers off a cube and give it a shot. I went with a set inspired by the Mad Titan himself, frocked with the Infinity gems on each of its 6 sides.

Edit:yes they are for sale, heres a link to my sticker shop https://soupcan13.com/stickers

Edit 2:since a couple folks have asked the decals are 16mm x 16mm but I can print/cut to pretty much any standard size

Here's the cube I used for a model
