The box turned out amazing! Thank you so much for the BoM, it made the project so much more achievable!
Small changes I did from the original:
Used a 2170 cell and a TP-4056 based BMS/Charger.
Added a USB-C plug on the bottom to enable charging without opening up the case
I printed the body on an angle primarily for the rainbow effect but it had the added benefit of not requiring the M3 square nuts (which I couldn't source in time for the gift) as the screws just threaded onto the plastic. It was surprisingly secure since there's nothing to grab onto the back cover its difficult for it to fall off in the first place.
