Summary A 3d printed swerve module. The drive axle is a 3/8" bolt. All hex shaft is 3/8" hex.
This was designed to interface with Vex Robotics motors. This allows users to teach about swerve concepts at a fraction of the cost of a FRC sized robot and control system.
It utilizes 4" wheels.
Bill of Materials (Per Module): 2 Side Panels 1 Top Plate 1 Top Spacer 1 Vex to Hex Gear 1 60T Vex Gear 2 Bevel Gears 1 30T Gear 1 54T Wheel Gear 1 Drive Shaft Spacer 1 Drive Axle (0.375" Hex, Minimum Length: 2.5") 1 Bevel Axle (0.375" Hex, Length: 3.125") 4 FR6ZZL-hex Bearing 4 3/8" id Flanged, Shielded Ball Bearing (FR6ZZ) 1 3/8" Bolt 1 3/8" Luck Nut 16 #10-24 screws (10 minimum, 16 if every mounting point is used) 4 #10-24 nuts 1 4" Wheel (I used the 4" HiGrip Wheel, available from AndyMark)
The base plate is good for adding visual appeal to a robot, but currently lacks enough structural stability to function as a sole mounting point for the swerve modules if printed. The spacing however is correct for all motors and gears, so I can also be used as a template for working on other materials.
Rafts and supports are not required. I used 0.2mm layer height. Infill: Varies depending on the part, generally, values above 20% are sufficient.
