Hearing Aid Battery Holder - Keychain

Update 5/28/19: As requested by calania 1mm diameter was added to the bottom part of the design to prevent common breakage at the thread location. This also required an extra 1mm be removed from the Top threading to allow for the larger bottom diameter. The latest files for print are the HearingAidBatteryHolderTop/Bottom - 1mm Diameter Added.stl. These files were test printed at .1 resolution w/support everywhere and printed out perfectly.

I am always looking for inspiration for my projects
