After a success of previous models (first upload on 5th December 2019), I decided to improve the model by reinforcing the adaptor. If you have an old camera that uses mercury cell batteries - PX32, EPX164, PX164A, HM-4N, or 164PX - I designed this adapter to allow you to use four LR44 replacing those old mercury cells that are no longer allowed and produced. Just print and add a copper wire, and voila! You can install the batteries any way you like, just make sure they're in the right direction on the camera, which is why I didn't draw the position of the poles on the adapter. For those who need it but 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 works 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), and E164 (Eveready) batteries. Designed to save material and weight. Model Dimensions: Height: ~45mm (44.9mm) Diameter: ~17mm (16.97mm) Print Settings: Rafts: No Brim: Yes Supports: No need Resolution: 0.2mm/layer (dependent on the nozzle diameter) Infill: 30% Print Temp: 205°C Build Plate Temp: 60°C Post-Printing Help: There is no need to sand 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 pictures to see details. It's super easy to do. It can be used in any position or direction on the camera, just check if the batteries' polarity matches with the camera's 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 a nail.
