I completely dismantled my Roomba, which is an older model 694, to clean it out and while it was apart I took measurements of everything and modeled it up in fusion360 so that I could make custom parts for it. I figured some other people could use it to.

I cannot gaurentee it's 100% perfect, but I do know that it's accurate enough that I was able to test print new bumpers to check the fit for the screw holes and it fit fine. I haven't made anything for mine yet but wanted to go ahead and upload this for others to use.
