20700 Battery Storage with a cover on magnets

thingiverse

I'm designing a custom battery box for two 20700 cells. The lid is hinged back and secured in place with a 1.75mm plastic thread. Two rectangular magnets, measuring 19.5x5x3 mm, hold the lid firmly in position. I've included Solidworks source files if you need to modify the magnet size or type. This case is designed for use with the IJOY Captain mod and should accommodate both 20700 batteries and the original 18650 adapter without issue.
