This is the largest and best looking clock in a series called "Crazy Gear Desk Clocks". The gears have been extended well beyond the dial and are continually in motion providing a very striking look. The gears have a new profile optimized for printing at a large size. The clock operates silently with a typical accuracy of better than one second per month.
A video of this clock is at https://www.youtube.com/shorts/ReKnLMyxin4
Additional videos showing assembly steps are coming soon.
The overall size is 14.75" by 15.0" (375x380mm). Total print time is around 80 hours on a Prusa MK3S using 0.9kg of PLA. The largest component will fit on a Prusa Mini or any machine with at least a 175x175mm print area.
The assembly guide showing the complete build instructions can be downloaded before purchase at https://www.stevesclocks.com/sp10
The primary non-printed components are:
   CNC Shield V4 or Silent Shield Clock Controller (Etsy)
   Ardiuno Nano
   TMC2208 stepper motor driver
   DS3231 precision real time clock
   NEMA17 stepper motor (0.9 degree step size is preferred)
   1/16" or 1.5mm music wire
   #6x3/4" or M3.5x20mm flat head wood screws
   M3x8mm screws
All of the parts are available on Amazon or other standard sources. The Silent Shield Clock Controller is a custom clock control board on Etsy at https://www.etsy.com/listing/1464560995  It is available in kit form, partially assembled, or fully assembled. A cheaper option is a modified version of the CNC Shield V4 controller. Instructions are in the assembly guide.

14-May-23 Update: Fixed a typo in the assembly guide and added a few additional diagrams. Typically, the most up-to-date assembly guide can always be downloaded from https://www.stevesclocks.com/sp10
17-May-23 Update: Added optional frame components with the legs merged into the center component. The file names are frame_*_merged.stl. They are not described in the assembly guide, but the steps should be obvious. The legs are pre-attached so the assembly steps to add the legs are no longer needed. They will need a printer with a 300x220mm print area.
 13-Feb-26 Update: Added merged frame components with the top handle. The components are named frame_?????_handle_merged.stl. These will require a large printer, otherwise print the segmented frame and connect components as described in the assembly guide. Also added frame components with the bottom corners of the legs clipped slightly to fit a printer with a 300x300mm bed. The file names are frame_?????_handle_merged_300x300.stl.

This is the 4th of Steve's clocks I've built, and I really enjoyed this one. His kit made it fairly simple, (if you know how to solder), and his instructions are superb, as always. Steve any chance you can build a cuckoo clock or something similar?
