Summary

  • A 3D-printable camera accessory has been designed to help cinematographers create a slick focus zoom effect.
  • The device uses a geared stepper motor, which is controlled through a set of printed parts that are attached to the standard 15mm tubing found on most camera rigs.
  • While it can be controlled via Arduino, the device also includes instructions on how to connect it to existing focus drivers.
  • The designers recommend using PETG or nylon for the gear wheels, but it will also work with PLA, albeit with a shorter lifespan.
  • There are already similar devices on the market, however, this is one of the cheapest options available at only the cost of the material.
