Yashica Electro 35 LR44 Adapter — PX 32, EPX164, PX164, HM-4N, 164PX

Yashica Electro 35 Battery Adapter /Yashica MG-1 (etc etc)
After a sucess of previous model (first upload on 5th december 2019), I decide to improve the model by reinforced the adpater.
If you have an old camera that uses mercury cell batteries — PX 32, EPX164, PX164A, HM-4N, 164PX — i've design this adapter that allows you to use 4 LR44 replacing those old mercury cells that are not allowed and produced any more, just print and put a coper wire et voilá!
You can install the batteries the way you want, just make sure you put them in the right direction on the camera, that's why I didn't draw the position of the poles on the adapter.

For those who need it and don't have a printer, i can print and send it with free shipping worldwide from ebay: https://www.ebay.ie/itm/283700556300?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649

This model work for essentially anything that uses those discontinued mercury batteries, but was designed specifically for the Yashica Electro 35 line of cameras. Some of the battery names/models in question are the PX32, PX450, TR164 (Malory), & E164 (Eveready) batteries.
Designed to save material and weight.

Post Printing help:
— There is no need sanding down for a friction-less fit in the battery chamber, but only a light sanding may be needed
— There is a hole in the print, going through the base, for electrical continuity. A copper wire will need to be threaded through this hole, and the ends bent. See pics to see details. It's super easy to do
— it can be used in any position/direction on camera, just check if the batteries polarity match with the camera polarity. The batteries should share the same polarity (direction) in the adapter
— The batteries removal are made to be easy, you just need to push with the nail
