26700 / 26650 cell battery bracket mount holder thing

thingiverse

I created a semi-modular bracket to hold packs of five cells and designed it myself. Unlike puzzle piece interlocking designs, mine uses holes that can be secured together with zip ties for flexibility in both pattern and orientation as well as literal flexibility within the pack itself. The concept is that the cell faces remain open for soldering directly to one another. My cells happen to be 26700s, but anything with a 26.5 mm diameter such as the popular 26650 should work just fine since the length of the cell doesn't impact this design in any way.
