Wall mount for Bosch Powerpack 725 battery for electric bicycle / cargo bike

sSince I couldn't find a wall mount for the Bosch Powerpack 725, I created one myself. 

Inspired by SeniorRossi (https://www.printables.com/de/@SeniorRossi_566649 )wall mount design, but unfortunately, it only fits Bosch Powerpack 500 batteries.

Considering the battery's weight of 4 kilograms, I focused primarily on stability during the design and printing process. 

For the printing parameters, I selected 

4 wall loops 

and used a 

honeycomb infill with 45% density. 

You could probably go a bit lower and save time and material. 

In this final print I used Tree Support but my test prints before where done without any support and came out fine.

For printing I used Bambulab PLA Though in black.

On my Bambulab printer, it took 5 hours and 40 minutes to complete the print.

Any comments or suggestions regarding this design are appreciated.
