21700 Puzzle Box

by lachtan86

Hey Makers, this is a remix of a brilliant design of 18650 Puzzle Box but for 21700 cell batteries. It is compatible with the original so you can combine a 21700 box with a 18650 box. It is based on the original design, however, enlarged for 21700 cells but the locks are the same as the original design.
