M42 Body cap

Handy for when you find old and dusty equipment without all accessories included… Printed with default Prusament PLA settings on a MK4. (Used PLA in pictures is generic PLA; @205 Degree C)

There is a M42 lensback cap too, in order to complete the set. :) 

Screws on perfectly on my LTL 3 Practica. Use at your own risk!

To facilitate easy screw on, there is a slight chamfer. IMHO it treads on easily.
