26650 battery tray

i needed a battry tray for 26650 sized cells. nothing i found online suited my purpose .
this tray will hold 3 x 2 cells.

i printed in PLA with 10% infill

outside walls are 0.8mm holes are 26.5mm and distance between cells is 1.6mm. The runs for the nickle strips should be 10mm.

Sides are flat so the tray can be expanded by gluing several together.
