Hey j0z, I love this design! I remixed it to get it working better straight off the print bed for my ender3 to put together as a gift for my dad, hope you like some of the changes I made! https://www.thingiverse.com/thing:3810972

Pendulum Clock - Improved

Hey! Thanks for working on the design, and posting pictures too! People like you inspire me to keep posting on Thingiverse; thanks again for sharing!

I'd love to get more updates on this in the future as well!

Best Regards,

Dug this the minute I saw it and had to have it! I had this done for me, as I don’t have a printer or the knowledge to do it! Works perfectly after trimming a bit off of every tip of the wheel and sanding it a bit!

Thanks for uploading that picture! I really appreciate seeing my work out in the wild; that photo made my day!

Got it working and will post a make tomorrow! I had to cut the tips of the wheel a little bit in order to make it work. My print made the wheel tips a little too long and cutting them did the trick.

Cool! It's great to see someone making this design!
I had some slight problems with that as well, but all it took for me was some quick sanding.
Feel free to message me if you have any questions.

Thanks for posting a make! I really appreciate it.

Hi j0z
Is it perhaps possible to show how the string thing gets attached? Perhaps a picture or video of how you did would help a lot.


That picture is being uploaded at the moment. You can see the explanation below I gave, as it seems that those instructions were very unclear.
Thanks for the feedback!

I would appreciate you posting a make as well!


Looks great and I am about to start printing my own.

I don't suppose you could upload a picture of what you mean by tying/sticking something to the wheel? I cannot see what you mean in the pics/vid.

Hi Jeremy,

I do not have access to the clock right now, but hopefully this explanation and attached diagram can help you.

If you look at the files, the backside of the wheel is a shaft.
You will want to glue (I used hot glue) or tie a string securely to the shaft, then wrap the string around, like you are wrapping the string around a kite or like how filament is wrapped around a spool. You will want to do this after the bearing is on and fit into the stand, otherwise the glue might prevent the bearing from fitting over. After the string is tied, you should hook or attach something heavy, like a key chain, to the loose end.

For the direction of this wrapping, the easiest way for me to explain is to tell you to wrap clockwise. This is if you are viewing the shaft side of the wheel.

If this is confusing, you can wrap it, then look at the clock's movement and check that it matches my video. The rounded teeth should push the pendulum like in the video; if you have it reversed, then the pointy teeth may hook onto the pendulum.

Thanks for the comment, and I would appreciate you posting a make!
Feel free to message me directly if you have any other questions.
