This clock looks like it will need a whole lot of support material. Is it possible for you to put the links in the description for all the parts, (electronics), needed to built this clock? I would really like to try this on my Ender 3. I have a working ball clock from the 80's. Are the ball bearings the same size? Thanks.

I remember those clocks. Had one as a kid. They used an arm attached to a synchronous (I think) motor to deliver the balls to the top. This has about as much coolness/geek factor as a binary clock. :)

I tried to minimize the amount of support needed where I could.

For the parts I got most from ebay, I'm not recommending any particular seller, the links provided is just the cheapest at the time of searching, the transistor, diode, resistor and capacitor are all common parts and the parts I used were what I had laying around, there are many similar type parts you can use instead. If you don't have those type of parts laying around it might be better to get a starter kit that contain various values of such parts instead of ordering a bunch of the same value.

Ball bearings need at least 29 and this link is for 25 so would need a quantity of 2: https://www.ebay.com/itm/25-3-8-Inch-G25-Precision-Chrome-Steel-Bearing-Balls-AISI-52100-Chromium-0-375/302714976608?hash=item467b37f960:g:7p8AAOSwbq9a3h14

80mmx60mm circuit board (max width that the holder can take is 77mm wide so would need to cut off one edge, if I had been thinking about standard size parts that other people would need to buy I would have made it wider so no cutting was needed): https://www.ebay.com/itm/1pc-6x8cm-Double-Side-Protoboard-Circuit-Universal-DIY-Prototype-PCB-Board-Rh/223066334407?hash=item33efca24c7:g:thkAAOSwyQtVqLss&frcectupt=true

I don't know what size bearings that clock uses.

Thanks for the reply. Have not tried to print this yet. Will try soon, and let you know how it turned out.
