Here is the most compact 6x2 spacer I could make with a 0.4 nozzle
This one is therefore not modular like other models of this type, this model is more intended to stick one next to the otherand is more intended for definitive assembly, the small holes on the spacer are not an economy of materialThey are designed to put glue and fix the cells together (I use silicone) and make an ultra solid and fixed pack. ( for a 70 cell )
I created this model to create an ultra compact battery for an electric scooter
be careful with your nickel strip, it can be used with 27mm on 6x2 cellBut it is not intended for more, it is better to find another nickel strip because the space between each cell is not the same as on most spacers
