Gameboy Advance Pokemon Ruby/Sapphire/Emerald battery holder

Battery in my Pokemon Ruby has run dry and I wanted to change it. I have skills to do so, but I couldn't source (or was lazy to search , to be honest) for new one with tabs, so I used pliers to “unroll” the tabs of the old battery and reused the tabs as a contact spot for new one.

I used this for years with electrical tape (and pressure of the cartridge lid) holding everything together. Then I got a 3D printer and made this model. It was trial and error and I knocked off one resistor so I had to fix that, but eventually I got to the point where it sits very nicely and doesn't bump into anything.

Buy CR1620 battery (original is 1616 I believe and it may work with this holder but it's untested). You print this out (using supports), put battery in, place it in the cartridge being careful not to knock into any resistors or capacitors (those really small parts on the board) placing it on the old battery tab covering big part of the chip the original battery sat on. While doing so, you put the other tab under the tab on the battery holder - this will help keep it in contact with the battery. Then just assemble the cratridge and there you go. You may need to fiddle a bit with the pads (bending them a bit) to have better contact, but once you do and you close the cartridge, you are ready to go. I tried it even without the cartridge lid and it still worked - the lid pressure is just kinda bonus to keep the battery in place and in contact with tabs.

It works with my Pokemon Ruby, I suppose Pokemon Sapphire and Emerald are the same.
