Description

A complete 60mm mechanical open differential and display stand. It separates the internal components—four spider gears on a central cross, two side gears, and a carrier housing—exactly as they sit in a full-scale axle.

The carrier housing splits cleanly in half to accept the cross and side gears, bolting together to secure the assembly. Three hex-driven input and output axles press-fit into the gears, allowing you to turn the pinion by hand and watch the side gears rotate independently through the spider gear array.

Assembly Notes

  • Hardware: Requires four standard M3 screws to clamp the carrier halves together. The lower carrier is sized for self-tapping, while the top has clearance holes and countersinks.
  • Gears: The bevel gears are toleranced for FDM with an 0.4mm nozzle. Press the three hex axles into the pinion and the two side gears.
  • Stand: The entire assembled carrier and pinion assembly drops into the U-slots on the display stand. No glue required.
