Jonction axe moteur (6mm) / roues de roller (22mm)

thingiverse

During my robotics workshops, the task of connecting the wheel to the motor shaft often poses a challenge for young students. To simplify this process, I've designed a set of two parts that make it easy to attach a roller or scooter wheel to a 6mm diameter motor axle without any modification. The design features four M3 screws integrated into the model, replacing the need for drilling. I encourage you to share your feedback and suggestions to improve this piece! This project is the result of my first creation using Tinkercad: https://tinkercad.com/things/1gTN3330gnU. Printing Settings: Rafts: No Supports: No Post-Printing: Installing Screws and Assembly This model is designed to incorporate M3 screws, eliminating the need for drilling. To assemble the piece, you will need: 4 M3 screws (three in the hexagonal holes and one in the slot for the pressure bolt) 1 M3x10 pressure bolt without head 3 conical-tipped M3x25 bolts After printing both pieces, use a pair of pliers and a work surface to install the screws. Mount the first piece onto the motor axle (pressure bolt facing the flat side), then screw in the pressure bolt. Next, attach a roller wheel with the bearings removed (22mm diameter) to the second piece's hub using the M3x25 bolts at an angle of 45 degrees to create even spacing and equal force distribution. The resulting assembly allows for easy wheel installation, smooth movement, and precise motor shaft alignment, ensuring reliable operation and long-lasting performance.
