3D Printed Sting 10 / 19C Battery Tray

[Jonas Sandstedt]

Hello,

I use the solution described (by me) at

https://www.hpmuseum.org/forum/thread-17716.html

and it works nicely.
Here the battery pack can be easily removed and safely charged outside the calculator, for example by an USB NiMH charger.

I have used a similar solution for an HP-97 with four sub-C celles instead, and it also works very well.

best regards
Jonas
