I used a HP 28S during the 80's at school....
In 1992, I lost my calculator in Spain (during olympic games).
After that I bought a Casio and used it years and years.
But Last week, I decided to buy a second hand 28S... to go back in the past!
I received it last friday!
It works perfectly but the battery cover is broken....
Do you have a solution ? Probably 3D printing?

Please help

Best regards from Luxemburg to all of you
