Bell & Howell Lens adapter to ELMO 16mm projector

This adapter lets you use a Bell & Howell cheap super 8mm projector lens in a 16mm ELMO projector 16-AL or 16-CL. You can use the B&H 1 inch f/1.6 lens as a wide angle lens for the ELMO projectors, so projection distance is shorten dramatically if compared to the 50mm ELMO default lens without investing in the extremely expensive ELMO wide angle lens. I have update the design so that the user won't have to remove of sand the pins that come out of the Bell & Howell Super 8 lens. I created two cuts in the solid that can house the pins.
