Coaxial Swerve Module

pinshape

A compact swerve module designed for 3D printing. The drive axle is secured with a sturdy 3/8-inch bolt. All hex shafts feature a standard 3/8-inch hex. This innovative design allows users to teach swerve concepts at a fraction of the cost compared to an FRC-sized robot and control system. It utilizes four-inch wheels for optimal performance. Bill of Materials (Per Module): * Two side panels * One top plate * One top spacer * One Vex to hex gear * One 60-tooth Vex gear * Two bevel gears * One 30-tooth gear * One 54-tooth wheel gear * One drive shaft spacer * One drive axle (0.375-inch hex, minimum length: 2.5 inches) * One bevel axle (0.375-inch hex, length: 3.125 inches) * Four FR6ZZL-hex bearings * Four 3/8-inch id flanged, shielded ball bearings (FR6ZZ) * One 3/8-inch bolt * One 3/8-inch lock nut * Sixteen #10-24 screws (at least ten, up to sixteen for maximum mounting points) * Four #10-24 nuts * One four-inch wheel (I used the HiGrip Wheel from AndyMark) The base plate offers a visually appealing design but lacks sufficient structural stability to support swerve modules as a sole mounting point. However, it maintains correct spacing for all motors and gears, making it a useful template for working with other materials. Rafts and supports are not required for printing. I used a 0.2mm layer height. Infill rates above 20% generally provide sufficient structural integrity.
