Ngàm ống kính Canon EF/EF-S

This is a printable model of the mount found on Canon EF/EF-S lenses, which you can use to design accessories like extension tubes or custom lenses.

Print at 0.1mm layer height, in PETG (recommended) or another filament like PLA. This is designed to be printed with the mount pointing upwards. Supports are not needed for the 3 mount flanges.

Two designs are included. One uses a 3D-printed slot for accepting the locking pin from the camera which matches that found on real lenses.

The other design has a space for a brass M3 hex nut to receive the locking pin. This suits high torque requirements (i.e. it prevents the camera's locking pin from tearing through a plastic 3D-printed slot if the lens has a lot of torque applied after locking). Please do use a brass nut here, because a steel one can scratch both the camera's mount and locking pin.

Design files have been provided in STL, STEP, and Fusion 360 project formats, so you can easily integrate this within your own designs.

The photo above shows the mount integrated into my Canon Variable Length Extension Tube design:
