About this 3D model

Here is the STLs and 3D drawing in Designspark Mechanical format (RSDOC) for 3D Printed Photography Lens Mechanism for Projector Lens. As this project was designed for Meyer Optik 140/3.5, I'm sure this will not suit to all projector lens, but hopefully gives the idea of the basic mechanism. Printed in 7 parts : M42 base inner tube + ring 52 outer tube gear + gear head + nut holder Happy printing :)
