Arrma Body Post with nut. Kraton, Outcast, Notorious, Talion, Typhon - AR320357

thingiverse

This rear body post replacement features a nut that securely holds itself in place using stock rubber holders, preventing loss. The initial screwing on might be stiff if your printer lacks precise print quality. Utilize a rag for improved grip on the nut and pliers on the body post to manipulate it up and down along the tread multiple times. With time, this will become exceptionally smooth. I have uploaded V2, which boasts a shorter, chamfered thread at the top and utilizes stock screws for mounting with an added washer from below. This design change was made necessary due to the central hole in V1 creating a vulnerable weak spot prone to breaking. 15/01/2020 - V3 has been added, offering essentially the same functionality as V2 but with slightly improved clearances.
