I can't help you AT ALL Drozd, but I hope someone else can.Also pretty excited to see what you're doing with this acrylic battery box!
Sounds cool Drozd,keep us posted on how its going.
it's kinda been slow going with it...
have had to cast the thing all together as a solid piece... then cut it apart to it's respective parts and then carve the insides...make molds for all 4 parts...and dry fit them...tweak and repeat the whole thing...
but since no one at all has a pre-made 18650 battery box on the market...*shrug*
it kinda evolved into a for purpose thing...
just don't know how easy it'll be for others to put together...
and if I have a bunch of leftovers and would want to give the extras away...I don't want to give someone something that's seen as a PITA impossible project..
as it stands it'll probably have to be put together in a very specific order...
