made some holders for my headway batteries so I can make a pack.
prints on standard size printer.
i've included the 123dx files so you can modify if you want.
Turns out my printer isn't super accurate and the holes printed 37.5 mm
also the cells are really 38.3-6mm
and I couldn't just scale up a few point because the 8 and up cell holder already took up the print base.
SO, I made a new set, the files ending with "a". the holes are 39mm, but will print smaller.
also the frame is a few mm smaller, so can be scaled a few points up or down.
Added a BMS mount
some sanding may be required depending on your printer
