Medium Crazy Gear Desk Clock

myminifactory

This is a medium size clock in a series called "Crazy Gear Desk Clocks". The gears are continually in motion providing a very striking look. The clock operates silently with a typical accuracy of better than one second per month. A video of the larger version of this clock is at https://www.youtube.com/shorts/ReKnLMyxin4 Additional videos showing assembly steps are coming soon. The overall size is 11.75" by 12.75" (300x325mm). Total print time is around 74 hours on a Prusa MK3S using 0.8kg 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.

There is a sub-forum set up specifically for electric clocks.   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 260x180mm print area. 22-Jul-24 Update: Added frame components with a top handle for better stability. The components are named frame_?????_handle.stl. A single #6x3/4" wood screw holds the pieces together, but be gentle since there is not a lot of depth on the threads. Also added logo.stl and a customizable logo_blank.stl to help hide the motor. Many slicers allow you to add custom text to the blank logo. The printed pieces slide in behind the front legs without taking the clock apart if you keep the text fairly shallow.
