SX70 Splitzer Adapter

This is a Splitzer adapter for the Polaroid SX70 based on Lomography's adapter for their camera's.

I've included two of actual lens mount which fits into the lens of the SX70. The first is fully open adapter which with the filter allows you to split the lens perfectly in half. The second is a quarter adapter which more closely matches the original by Lomography.
As well as the splitter filter. Printing the pieces separately means that the splitter can rotate freely from the lens.

Since the purpose of the Splitzer is double exposures I've also included a shim which can be used to stop the photo from printing between exposures based on this video:

NOTE: After a couple of tests I've found that the plastic shim occasionally provides just a tad too much resistance to the camera's motors. I'm leaving it in here because it is useful, but by using it you accept responsibility for it's
