double feed extruder mount

thingiverse

To enhance my previous double feed mount for MakerGear hot ends, I designed a versatile retainer clamp that allows either single or dual setup. Initially, I planned minimal clearance between barrels but changed my mind to enable 4 barrels with 20mm center-to-center spacing when bolted together back-to-back. Although the SCAD file is not parametric, it's easy to modify (and may be parameterized later). Due to size constraints on a MakerBot printer, I modified the mounting ears to be separate pieces.
