Battery Holder for HP 97 Calculator

If you are an owner of a classic HP-calculator like the famous HP 97 you may need a replacement for a lost or defective battery-holder.
This thing will enable you to build a battery pack with new cells. For a complete battery holder you will have to print it twice.
For the wiring of the cells you will find information in the internet or you just copy the connections from an existing pack.
I tested a rebuilt pack with a HP 97 and a HP 82143A printer. It fits and works well.
