I print these at 20% adaptive cubic infill. This gives enough strength for 5Ah batteries at least.
Alternatively you can print these at 40% infill with very similar time and material usage as the original model.
2x, 3x and 4x versions have spacing for 5Ah XR batteries. Wider batteries might fit but I can't verify this because I don't own any 21700 cell packs. Fusion files can be edited to change the spacing if needed.
Locking versions require supports for the locking surfaces. Automatic tree support in Orca works just fine.

This is a simplified remix that can be printed faster and with less material than the original or with higher infill percentage with same time and material costs.
