This is a magnetic battery cover for the ThermaPen One. Use two 1"x1/2"x1/8" magnets. You'll also need a M3x8 screw. Step up the usability of the Thermapen ONE! Stick it to the fridge, microwave, range hood, whatever.

I printed this using the standard profile for Bambu PLA Basic on a P1S. Enable manual supports and paint supports under the screw boss extension, and the two case hooks. Also use a brim. Insert a pause layer into your slice so you can drop in the magnets. Have fun, kids!
