About this 3D model

I was inspired by the project by Zach Swena an his idea about a low cost T-Bar. My solution to this problem is a 3D printed one. My printer just arrived so I started by drawing my idea in Corel and then the 3D I sketchup. My idea is based on 2 potentiometers and one of them is rotated 180 degrees and they are cross connected. I have tried this setup before and the result of this is an analog output spanning 0-5V if the supply voltage is 5V. This should work directly with Kasper Skaarhojs Arduino Library for the ATEM Switchers
