If you can find the spec for the gear (and/or gears) but not find anything stock available or affordable, you may be able to create your own 3D model(s) using a gear generator app.? I did this a few years ago for a woodworking project.? I was working with a vendor that would use a CNC router to produce templates of some gears I wanted for making the gear toy for my granddaughter.? I was a rank novice at Fusion 360, but after generating 2D drawings (model), I managed to extrude them in F360 in 3D models.? I sent those to the CNC router guy and he cut out the gear templates.? In the end, it was never completed, but producing the gears was a success.?
I used a meant for woodworking, but I see no reason why it wouldn't work for this.? I'm sure there must be others as well and there may be some that actually generate the 3D model directly.?
