I wanted a way to store a Sharpie on my deep freezer to allow adding dates and details to food packaging. This model has two 1"x ½"x .125" magnets inserted into the model during printing. I had these magnets around, or I would have used a more standard size. I can change the size if desired.

Mine are printed in Overture White PETG. https://amzn.to/3S22tc8

-Version 2 titled Sharpie Magnet 12 6mmx2mm uses 12 6mmx2mm round magnets and is untested, I am unsure if the 12 magnets will provide enough force to hold the mount. The first two layers need to be .2mm height to allow 2 layers to hold magnets. I will update after it is printed and tested.
