Front standard for a Polaroid 900 camera with trigger.

Parts to make a front standard for a polaroid camera to change the lens for a copal shutter.
You will need a set of 4mm pins and also a set of 3.2mm pins.

The standard would be better done in aluminium for rigidity, but I leave the option to print it to you.

You will also need a spring for the trigger, to be placed underneath.
