Canon EF lens adapter for GuerillaBeam projectors

Designed for attaching Canon EF lenses to your Guerilla Projector. Could be useful for other projects too. The method for attaching the lens is unique and better suited for FDM printing than normal bayonet mount adapters. The lens is firmly gripped by the adapter and secured in place by the 53x3mm screw on the opposing end. See https://gbeam.de/products/canon-ef-lens-adapter/ for further details.
