This is a pendulum clock I made as a fun project inspired by a UC San Diego undergraduate course. The ticking mechanism is called an escapement, and is often used in other clock mechanisms.

To get it to work, you need to attach a string to the shaft of the wheel with glue, tape, or any other method after completing assembly (with bearings and the stand). Once the string is attached, get something mildly heavy, like a keychain, and attach it to the loose end of the string. Wrap the string around the shaft like you are winding a kite string or like how filament is wound around a spool. The weight turns the wheel, and the wheel pushes on the pendulum, causing it to swing like in a grandfather clock.

This clock is designed to use 2x 608 size skateboard bearings. Everything else is 3d printed, and tolerances to fit the bearings are already built in. STL Files are in mm. Also, you may want to cut the bracket in half or make it out of a different material i.e. lasercut, etc.

You may want to use some glue to permanently adhere the pieces, especially the bearings- I used hot glue and it works fine.

Hope you guys enjoy, remember to like and post your make!
