M42 Lens Adapter

youmagine

This is a custom-made adapter designed specifically for M42 and T2 manual lenses as part of the innovative GuerillaBeam project. The adapter functions by securely fitting into the naturally occurring undercut of the M42 screw thread, allowing it to be firmly locked in place using a female screw. Created with versatility in mind, this adapter is tailored to fit seamlessly on a GuerillaBeam projector, and its design may also make it suitable for other projects requiring this type of connection. To produce the adapter, I use my Ultimaker 3D printer, printing it in PLA material at a layer height of 0.3mm with a print speed of 60mm/s; however, achieving a higher level of detail is possible by reducing the layer height to 0.2mm.
