Hmm while I see your point, I was going for conciseness and I think it's reasonable to assume that extra parts are required - we can't quite print stepper motors at home yet! The rest of the basic requirements is nuts/bolts (standard kit stuff), and a $5 microcontroller[1]. (Things like the aluminium base can also be 3D printed, but it's not recommended for stability. There are lots of optional components that greatly improve usage.)

I think GP's point isn't off the mark here, but also that the title doesn't need to be altered. There's no need for any additional electronics to construct a Dobsonian and mount capable of manually tracking DSOs, for instance.

I say this as someone who uses "computerized" and EQ mounts, but I also assumed from the title that this was a completely 3D printable project (sans mirrors, I can print my own washers and bolts), which is way more exciting a prospect than having to buy or put together a fairly complex kit, just not all of it if you have a 3D printer.

I just 3D printed a custom IR CCD mount for my CST, but I'm very interested in adapting this to some of my designs, so thank you for sharing!

Oh sure, but in my defence a simple Dob eq platform hardly requires any software, so 'open source' would be a strange thing to point out ;) A lot of the hard work is the custom PC software & getting it ASCOM compatible for autoguiding, etc.
