Bosch 14.4v battery lower case

Disclaimer

Batteries can be dangerous if mishandled. Use them safely by applying common sense and best practices. You have been warned.

Prerequisites

• Bosch 14.4v battery, refer to photos for the compatibility;
• 18650 batteries, 8x;
• Charge controller, 40A 4S;
• Printed parts:
  • spacer 1x;
  • battery_bottom 1x;
  • spring 2x;
• Video guide.

Everything except the battery cells and bottom part of the battery case will be reused from the original battery. 

Misc

The size is identical to the original expanded capacity batteries, so it fits most toolcases.

I suggest printing in ABS. While modeling, I took into account the ABS shrinkage.

Parts are printed supportless; be sure to print the springs horizontally.
