Let’s Build: 3D-Printed Mechanical Clock, Part 2

New parts may have to be printed as we continue to piece this 3D-printed clock together. But with a little bit of tweaking and lots of trial and error, we have a successful build!

  1. Changes that we made that eventually worked:

    – Closest equivalent rods – 1.5mm = 1/16″ – 2mm = 3/32″ – 3mm = 1/8″

    – Lubricated axles and pivot points with sewing machine oil

    – Used alternate 1.5mm thick spring: https://www.thingiverse.com/thing:1093256

    – Made sure spring did not rub adjacent gear or balance wheel – required some strategic tape placement to pull it one way or the other

    – Used higher infill on balance wheel for more weight

    – Spring/balance wheel connection should be snug – added teflon tape to make it so

    – Length of rods is very important

    – Had to add more weight – think about 2 – 2.5kg total

    – Decreased size of holes on hands for tighter fit

  2. Grrrreat stuff, kind of want to do stuff like this as well. 🙂 Bit weird on headphones with the noise cancellation in the video.

  3. Can I just say Shaun, I love your attention to detail, instructions and sharing of solutions. That is what making is all about.

  4. So inspiring! Even though there where some hiccups this is another example of how the Maker Comunity is all about opening doors for people interested in different disciplines. If you are interested in how clocks work, have a 3d Printer, and enough patience you can build a functioning clock….. pronominal. Thanks Tested Team!

  5. I am attempting to build this clock, and with your video I think I have a fighting chance at it. I had noticed you have changed the clock face to numeral numbers as well. I searched and cannot find this stl. Could you download or give me an idea where you got this. Thank you.
