Helical Gear High strength die steel Material Gears Upgraded 3d Printer parts for mini V1 V2 double gear Sherpa extruders

**1. Performance characteristics of helical gear:**
- The meshing performance is better. Compared with the spur gear, the helical gear meshes more fully during the transmission process, the gear transmission is more stable, and the transmission force is more linear;
- Long service life. The helical gear transmission has a large coincidence degree, a long meshing time and a large contact area, which makes the stress smaller, thereby improving the bearing capacity of the gear and prolonging the service life of the gear;
- The structure is relatively compact. The structure of the helical gear is relatively compact, and a smaller gear mouse can basically bring about a relatively ideal deceleration effect.

**2. Purpose:**
For other extruders that use double gear pairs, such as mini V1 or V2 extruders, Sherpa metal extruders, Sherpa extruders, etc.
