This is a rear body post replacement with a nut. It's designed to hold the nut with the stock rubber holders so you don't loose it. First screw on might be tight if your printer does not print very accurately. Use a rag for better grip on the nut and pliers on the body post to work it up and down the tread a couple of times. It wil get super smooth with time. I've uploaded V2 which features a shorter and chamfered tread on the top and uses the stock screws for mounting with a washer from the bottom because the hole in the center of V1 creates a weak spot and it's prone to breaking. 15/01/2020 - Added V3 which is essentially the same thing to V2 but with slightly better clearances.
