Stromer ST2 battery holder for rack

A battary holder for a second battery for your Stromer bike.
I can still attach a bag to the side.

You may have to adjust the size slightly (my 2 batterys differ in size by 1 or 2 mm).


My print settings:

I used PETG rather than PLA because it has little more flex (needed for the seat post clamp) and good layer adhesion.
I used a 0.6 mm nozzle for faster printing.

frame:
100% infill

endcap:
5 walls, very little infill, no support necessary

hook:
1 wall, 100% infill
