For a hobby project, I'm designing a clock with a single hand that makes one revolution per year. Using really helpful sites like https://geargenerator.com/, I have the gear ratios and dimensions worked out, and now I'd like to start prototyping.
What's a reasonable way to get some gears made for that? I don't want to spend a lot of money (this is just something to hang on my own wall, probably) but I do want the gears to function correctly.
Is 3d printing a good option for gears, or will they need to be machined? For scale, I think the largest gears will be about 2-3 inches in diameter with around 80 teeth. If machining is necessary, are there different quality options that affect price?
For the curious: my gear ratios are 8:83, 8:59, 8:47, and 8:13. That comes out to 4096:2992067, i.e. 0.5:365.2426 - so a motor designed to go around twice per day (a clock hour hand) should slow down to once per year (including leap years!).
Obviously there's probably some pretty basic stuff I don't know, like whether people usually work with gears in standard tooth numbers or whether weird numbers like the ones I have are accessible.
Thanks for any insight.
