Just replaced the engine in my 07' ranger 4.0l. Replaced all timing components and all kinds of things. I was a complete idiot and removed the metal sleeve from my rear main seal thinking it was only to protect the seal during shipment (honestly don't know what I was thinking lol). Long story short, I've got a bad rear main seal leak now and I'm pissed.

I don't want to buy a tool I'm going to use once (let's hope it's only once), so I'm thinking I could 3d print the tool. Now before you yell at me that 3d printing it is a stupid idea, let me say that the 3d printer I have access to at work prints really durable and tough plastic. From the videos I've watched I really think it would be strong enough to install this seal. I may be wrong but I figured why not try? In order to do this though I need to know the dimensions of the tool! I could always buy one, measure it, then return it. However I figured someone on here has the tool and could dimension it (the two main parts) so that I can draw them up in my CAD software and get them printed. Can someone help me out with this?
