This is an easier and quicker option to print than most of the others.
Basically the lite version of my other one.
Use 2 EZGimbal, 1 on the mount, 1 on the nut, and put a "The Purcellx1" in the middle.
The 2nd pic with red parts and alum mount is of this setup.
Currently, I think this is the best option here for what it does, ease of print, and assembly.
Added EZGimbal v2
A little more clearance and smoothed the corners for an easier print.
Added "The Purcell"
This needs 2 "The Purcellx2", 1 "The Purcellx1", and 4 .177cal BBs.
The BBs go in one direction on the upper level, and the other direction on the lower level.
