I was looking for a cool design for my micro:bit on the Christmas tree and found Kitronik's (https://kitronik.co.uk/blogs/resources/mipower-microbit-christmas-baubles) page. Their perspex designs caught my eye. Since I don't have a cutting machine, I used my 3D printer instead. I changed the design files into .STL files so others can enjoy them too!
