3D Printed Chaotic Pendulum with Ring and Bar. Normall and small size
Description
First I made the regular size pendulum and then the small one. They are meant to be mounted on a wooden base. The regular size pendulum has holes (11mm) for placing a led light. (optional) What you will need for the regular size pendulum: - 4 608 (8x22x7mm) (skateboard) low friction bearings. - some washers (9mm) for extra counterweight and ballancing. - 4 M3 screws. What you will need for the small size pendulum: - 4 MR115-2RS (5x11x4mm) low friction bearings. - some washers (6mm) for extra counterweight and ballancing. - 4 M3 screws. Remarks: - Support is only necessary for the pendu_bolt and pendu_bolt_small. - The bearings are friction-fit and it is possible that you have to slightly file down the shafts and axis for the bearings. - If you don't have low friction bearings you have to degrease the bearings with alcohol or the friction will be too high. (Remove the plastic cover of the bearing and apply alcohol. Optionally you could then add some low viscosity oil.) Video1: https://youtu.be/fPRYcxA0mBM Video2: https://youtu.be/gwIyjFtjDgg
