Powerbank for 18650 Battery

I had a power bank for a 18650 battery. After I had inserted the battery incorrectly and thereby the electronics burned out, I wanted to replace these. The spare part that I ordered, but did not fit. That's why I decided to design and print the case myself.
The design was created with OpenSCAD. This is my first design that I publish. I would be very happy, if someone has use for it.

I used the AZDelivery Power Bank Modul Laderegler TP5400. You will need some wire for the spring of the negative pole and some metal sheet for the positive pole.

Feel free to use and customize the design.

I've published this design first on Thingiverse.

Note: I've printed the inner part with supports. I don't know if it is necessary.
