Open source odometry or dead wheels for FTC using some TETRIX and Andymark parts. Full wheel.step: full assembly of the part New dead wheels - face 1 / face 2 / middle.step: the Omni wheel Side plates - body.step: the body that the wheel and encoder attach to Non-3D printed parts: -TETRIX PRIME bronze bushing; https://www.pitsco.com/TETRIX-PRIME-Bronze-Bushings -TETRIX MAX Omni Wheel (just for the rollers); https://www.pitsco.com/TETRIX-Omni-Wheel-Packs -E4T OEM Miniature Optical Encoder Kit; https://www.andymark.com/products/e4t-oem-miniature-optical-encoder-kit?via=Z2lkOi8vYW5keW1hcmsvV29ya2FyZWE6Ok5hdmlnYXRpb246OlNlYXJjaFJlc3VsdHMvJTdCJTIyYnV0dG9uJTIyJTNBJTIyc2VhcmNoJTIyJTJDJTIycSUyMiUzQSUyMmVuY29kZXIlMjIlMkMlMjJ1dGY4JTIyJTNBJTIyJUUyJTlDJTkzJTIyJTdE -TETRIX MAX Axle Hub 2X; https://www.pitsco.com/TETRIX-Axle-Hubs -TETRIX MAX 6 mm Steel Axle; https://www.pitsco.com/TETRIX-MAX-6-mm-Steel-Axle The servo and parts used for mounting: -TETRIX MAX Standard-Scale Servo Motor; https://www.pitsco.com/TETRIX-MAX-Standard-Scale-Servo-Motor -TETRIX MAX Servo Horn; https://www.pitsco.com/Servo-Horn -Any servo mounting plate will work Assembly: 1. 3D print files: "body", "face1", "face2", and "middle" 2. Assemble the wheel using "middle", "face 1", "face 2", and rollers from TETRIX MAX Omni Wheel 3. Using screws with a thread length of at least 37mm assemble as seen in the "full wheel.step" file 4. Disassemble the E4T encoder and remove the lens of the encoder (to protect it during assembly) 5. Attach the body of the encoder to the "body" 3d print via the small holes on the side under the larger hole; the mount for the encoder may not be included in your kit, in which case attach the encoder in any way securely to the outside of the "body" print so that they are centered around the large hole. 6. Press the bushings into the large holes from the inside out on both sides of the "body" print 7. Push the lens of the encoder onto the axle and slide the axle through the encoder, side of the "body" print, the fully assembled wheel, and out the other side of the "body" print 8. To attach to the servo for mounting drill holes in the thicker part of the "body" for screws to attach the servo horn
