FireGear is the FirePick repository for 3D-printed (3DP) gears shared by multiple FirePick projects. The gears are organized into collections that work together:
Herringbone gears are familiar to anyone with a 3D printer, since they are used in the 3DP extruders to drive the hobbed bolt. Herringbone gears are self-aligning, which makes them ideal for transferring power between 3DP plastic parts that can wear and flex. They also minimize backlash on changes of direction.
Triangular herringbone gears are not involute, which makes them noisy and inefficient in comparison with involute gears. However, it is much easier to design and customize triangular gears with minimal effort.
FireGear will eventually include involute gears that can be used to replace H20 gear combinations with their involute counterparts.
FireGear also includes flywheels for increasing the performance of your stepper motors
FireGear washers have known dimensions for specific use. Regular metal washers may work as well, but their dimensions are rarely consistent.
FireGear tools have dimensions for specific use. Regular metal tools may or may not work as well, but their dimensions are rarely consistent.
