True 18650 Battery Holders (x1, x2, x3, x4)

For now, see the remix for printing and assembly instructions. I printed 200microns, 3 walls (1.2mm for 0.4 nozzle users), 50% infill, lines, grid or gyroid will do. Supports (grid) are recommended. They are easy enough to remove. Keystone 209, which is ground, snaps in from the top (longer air gap side). Keystone 228, which is positive, snaps in from the bottom (shorter air gap side). Route wires as you want with the channels underneath. 22AWG worked best for me. The x2, x3 and x4 are parallel. I may add a series version soon, of course you can always "wire" them in series. Who knows. (fixed wire channels for x3 and x4) Note: They are a bit rough on the shrink tubing so avoid removing the batteries frequently.
