ebox mosfet single 18650

Please be kind. this is my first thing i ever designed and printed, i am very proud of this item and i know it still needs some fine tuning.

updated 5/2:
created a belt holster for ebox mod. Print with support, scale up 0.01 if you don't feel like sanding

updated 4/26:
moved charging port to side so it will stand when charging, no more leaking vaps.
created a cut on battery holster for easier access to screws for momentary switch.


updated 3/22:
as per request i have uploaded base with support for a 12mm switch. i have over-sized it by 0.4 mm making the hole 12.4mm allowing any 12mm switch to slide in smoothly

update 3/21:
wired up the box mod. everything fit as i wanted. i uploaded more pictures of the wired box.
