For an option that doesn't require the use of an AMS, check out this model.

After remixing this clock originally, I got an AMS and wanted to print the face smooth and face down to save on filament and have an awesome look.  So, I modified it again to print flat, facing down.  I printed this with a 0.2mm nozzle because I really wanted every detail to be the best, but feel free to try it with a 0.4mm nozzle and add your print profile if it works for you.  There are some small supports in the hanger hole, so be sure to remove with some tweezers before hanging.

I also added a mini Elder Wand as the minute hand and Harry Potter's wand for the hour hand, which can be printed in any color you like (the clock hands plate prints by object to minimize color changes if printing in multiple colors).  Enjoy!

This is meant to be used with the Bambu Lab Clock Components Kit 011.
