5209 keystone holder

thingiverse

I'm fed up with constantly reinserting a worn-out battery contact that starts to become dislodged after several insertions. To improve the bonding surface, I designed a holder with a thickness of 1 millimeter, ensuring it slips in securely without cluttering the area. The dimensions are compact and precise, requiring tight tolerances. If you don't have a highly accurate printer, you'll need to scale the file by 10% and secure the contact with a small amount of glue. However, if you possess a very precise machine, you should use a 0.2-0.25 millimeter nozzle and clean filament for optimal results. That's all; great job!
