I planned to use a steel fabric pin for the pendulum axle because I thought it would slide across the magnet but stay in place. When I tried to swing a pendulum like this, it had more friction than anticipated. I revised the axle holes to be big enough for easy movement.

I modified the base to include slots where I can add small strike plates, drums, that the pendulum will strike. I made six sizes of square panels to mount in the base, but I should have added a hole for the central bolts. I cut all the parts with my laser cutter.

I will not need to print more of the simple cross members because that design has stayed the same recently, and I have a surplus. I added a couple of interface rings to this addition that let me easily stack the black standoffs and make the case taller. It was challenging to assemble the pendulum to the spinner inside the cage, but it was still easier than removing the top.

Sorry about the unsteady camera work
