This is a project to make small colored magnetic blocks to make different things out of. Imagine a real-life minecraft. This particular model is a 5mm cube with a cavity in the center for a 3mm magnet purchased from amazon. My first test was with a 6mm shell surrounding the magnet. Magnetic strength drops exponentially and so the smaller the gap between magnets, the better the strength.

This video shows you how to use cura to pause on certain layers. In the case of the 5mm version, the pause layer is 4.1mm.
