DH Speedbox

The DH Speedbox is designed for adding a 1:3 gearing increase between the Nema17 drive motor and the cable for a Zesty Nimble.

Note: the ring gear in the ring stand acts a little under-sized currently. Scaling X and Y to 103% seems to work until I can correct this issue permanently.

Hardware:
- (5) m3x8 machine screws (button head hex screws recommended)
- (1) m3x10 machine screw (button head hex screw recommended)
- (1) m3 hex nut

Optional Hardware:
- Extra long Nema17 motor (more torque for higher speeds and/or tighter cable bends)

Features:
- Only need fasteners to install
- Double Herringbone (DH) gears to provide inherent stability within the gear train
- Designed for easy install

Notes:
- This WILL increase the amount of torque needed to drive the Nimble
- A pancake motor will not work
- 1:3 ratio means 3 times the torque needed to go the same speed.
- This is a lossy drivetrain, lubrication will definitely help (I use a spray-on silicon lubri
