SP12: Crazy Gear Wall Clock

​

This is my largest clock with the best features from my previous clocks merged into a great looking design. It is a vertical orientation wall clock with oversized gears and the escapement right up front. 

​

The gears use the crazy gear layout from the crazy gear desk clocks.

​

Everything is easy to assemble using only a few screws, similar to the easy gear wall clock design.

​

The pallet and pendulum have a solid connection to improve efficiency and allow runtimes up to 15 days.

​

The overall size is 23" tall, 9.5" wide, and 7" deep (580x240x175mm). It requires a printer with at least a 205x205mm print area. A Prusa MK3S or Ender3 will work great. Total print time on a Prusa MK3S is 140 hours using 1.5kg of PLA.
