This is a larger 55-tooth gear for the Heden M21VE/M21VE-L lens motor, allowing you to dig into hard-to-reach iris gears like the 15/18/135/150/200mm Zeiss Supreme Primes, and modern rehoused lenses from TLS, Zero Optik, etc which have the iris gear very close to the PL mount.
The stock size of the M21 gear is barely larger than the diameter of the adjacent motor housing, so sometimes the motor will collide with the lens barrel or PL mount before the gear is fully meshed. This larger gear solves that.
Reuse the gear carrier from your existing gear, but you need 3x M2x10mm flat head screws.
Printed with PETG-CF but some form of nylon PA6/PAHT/PA12 with CF would be ideal.
