AA, AAA and 9V batteries pilot chamber

update 1/13/2022 I have created a small extractor with a glued magnet, from an old hard drive, about 14 mm in diameter, held with a clip that is attached to the pilot's chamber. I realized that it is a bit difficult to remove the batteries from their housing horizontal size offset of -0.1mm I have combined the left AAA launcher with the right AAA launcher, and I have added the pilot chamber for 9V batteries, vertically superimposing 2 pilot chambers, to make the hole bigger, with tinkercad. To print, (simplify 3D) all the pieces have a horizontal size compensation of -0.2 mm. except the base of the launcher which has a horizontal size offset of -0.1mm.
