Yashica TL-Electro Battery adapter
thingiverse
UPDATE: Silver oxide 357 1.55v batteries work much better instead of 675 zinc air batteries. You can shoot rolls continuously, and the meter appears to be accurate according to a light meter that I use. This is a battery adapter for the Yashica TL Electro to allow it function due to the ban of mercury batteries. It requires two 675 zinc air hearing aid batteries, and some washers. Batteries should be on the bottom of the adapter and the top with washers in between. I used 6 brass washers (id: 5.6 mm; od: 12.9 mm) and 3 steel washers (id: 4.8mm; od: 11.4mm). This adapter gives life to your Electro TL once again. PLA or ABS work fine for this print, but the smaller resolution that it is printed, the better the outcome. May fit some other cameras as well.
