Construction Wheel Free 3D print model
This part is a one piece construction kit with a centre hole so it can act as a wheel or rod end, and also slots which support axles and fasteners like rubber bands. For strong joining rods on functional models use 3mm timber or fibreglass rod, for weaker rods on static models use Yakult straws or cotton buds or anything else you can find. Sofar, miniature towers, flowers, 4 wheel steering cars, carports, and self propelling cars have been built using the part. What can you make? Can your car go further than your friends when you wind it up or roll it down a hill?
