15mm Rail Mount For NEMA 17 Follow Focus Stepper Motor

thingiverse

To overcome the limitations and costs of existing follow focus systems, a custom solution was created as part of a larger motion control rig. The system utilizes NEMA 17 stepper motors and requires reliable mounting for smooth operation across various cameras. For quick transitions between cameras and lens changes, the design features easily printable parts that have proven flawless since implementation. User satisfaction has led to hopes of others benefiting from it as well. For optimal strength, a 10% infill is recommended; however, 100% infill can be used if desired. Assembling the system requires a 3/4 inch long 1/4"-20 screw and a hex nut along with four M-3 screws for secure stepper motor mounting. The 15mm rail clamp offers suitable support, ensuring seamless functionality. Gears for the stepper motors can be sourced from Servocity to complement the system.
