Part of my problem is that I don’t have a mature vocabulary to describe the things that I’m after, so please bear with me.
I’d like to take a hobby motor, like this, and create a 3d printed object that can fit onto that gear. How do you go about doing something like this? I suppose I would take a front-facing photo of the gear, bring that into Sketchup, align with a ruler so that it’s the correct scale, and then start to design around it, creating an inverted “female” end for the motor gear. Does that sound reasonable or is there an easier way to approach these kinds of things? Seems like it would be a common task but I can’t find any info on it, likely because I am using the wrong vocabulary.
Any help appreciated. Thanks!
