Over the past several years, I've used many different cell holders for testing batteries. I've tried many options from the cheap leaf spring cell holders to expensive aluminum-framed universal cell holders, but none of them got everything right. So I designed my own to try and get as many things right as possible.
I printed everything on my Prusa Mini in standard PETG with a 0.6mm nozzle. The parts use about $2 of filament and take about 4h.
The cell holder base needs a pause after completing the holes for the captive nuts so you can insert 4x M3 nuts. For a guide on pausing a print after a specific layer in Prusa Slicer, see here.
The files include a single object with many parts. All except the large base piece are modifiers. The modifiers should be changed to 100% infill, except for the ones at the bottom under the cell which needs 15% hexagonal infill and 0 perimeters, 0 top layers, and 0 bottom layers. For a guide on using modifiers in Prusa Slicer, see here.
If you're interested in finding the rest of the non-printed parts for this build, there are kits for them on my own website here, or on Tindie here.
