Clock Forum

Your clocks are fascinating, and I'd love to make one. I don't own a 3d printer (yet) and am just learning about 3d printing. I don't have a big budget. What size of a printer would be appropriate? I've seen the Creality Ender 3 for sale used at a good price. Would it be good for clocks? And what features should I look for in a printer to get good gears? Thank you. I look forward to building one of your designs.

Afternoon- I am fairly stumped....I have rebuilt and (I thought) verified everything in my 10 day easy build a couple times, but I can't seem to figure out this issue. All assembled, the pendulum will run for hours and all the gears turn except the ones that actually tell the time. From what I can tell Gear 4b, 5, and 6 do not move. I can't tell where the energy seems to be disappearing. I am currently printing the updated gears 3 and 4 to install, so I'll have the clock back apart in a bit, any quick thoughts on what I might be a culprit that keeps my clock from telling the time? Thanks

Hi, I am prototyping a clock of my own, and making many (hopefully instructive) mistakes along the way. I wanted to ask about something you mention briefly in the PDF that accompanies SP1. You say that the arbor spacing was increased for the gears to mesh properly (top of page 8). Do you have a rule of thumb for doing this? I am using the standard approach that for two gears with X and Y teeth and module m, they should be (X+Y)m/2 apart, or something similar if you use DP. In some places I can see that this makes the gears too tight, whether due to printer tolerance or because the load on the gears puts a bit of sideways pressure on them. I'm experimenting with this, and if you have any guidance it would help the process along.
