I was getting very interested in analogue stereo photography after seeing some old negatives. so after collecting some old stereo cameras was it also time to make some experimental ones based on the ICD 1.  but in classic fashion did I start out with a screw driver and a box to test the rough concept out. before I committing to making a wooden model. I and later did I also made a Pinhole adapter kit (PAK) for the ICD S1.
