InMoov Neck screws resized

Last crawled date: 5 years, 9 months ago

This is a remix of the "neck piston side v1" as seen in the neck gallery on the inmoov.fr website. I was unable to get the pieces to not jam together with the stock design on my printer. So what i did was resize just the x and y scale of the threaded portion of the piston. the overall length is the same as it was, the bottom that accepts the servo ends hasn't changed at all. I made a few different scales from 99% to 96%. I found using a 96% to run in and out of the neck piston a few time that allowed a 97% to fit in tight but still allow for the motion to work as intended. After a few dozen to a 100 screw in/out cycles i lubed the pistons threads with belray motorcycle chain lube. Im pretty sure it is a ptfe lithium mixture that sprays on. Once lubed the pistons function very easy and smoothly.
