The file 'Manual Shutter Battery Compartment For 4×5 Polaroid 3D Printer Model' is (stl) file type, size is 24.1KB.
This is a combination of Hackaninstant's battery compartment for his 4x5 back conversion and his Arduino-based manual shutter speed conversion. All credit for the original design and concept goes to him!
The guide to convert a Packfilm camera to a manual shutter can be found on his GitHub page: https://github.com/hackaninstant/Polaroid-shutter-control
I would recommend cutting the OLED display pegs shorter or off completely as the display already is friction fit. The push buttons are also friction fit, I pushed mine up to the legs and they seem to stay as long as they are not pressed with a massive amount of force. The switches are held down by melting the pegs over the metal tabs. The forward-facing display cover might also need sanding down to fit. My example also does not have labels or the wiring yet.
I found my switches and buttons on Digikey and my SSD1306 OLED on eBay.
