40x120 Extrusion

This is the same as atancito's "Aluminum Profile 40x120 - A simple aluminum profile 40x120x200mm", except I fixed the mesh errors that were causing Cura to not properly render the vertical holes in the center and right side sections. YMMV with this one in regard to quality of the STL as I had to take the STL mesh, stitch and repair it, Generate Face Groups, convert mesh, then rebore the holes. 6.8mm seemed to be what the original holes were.

Do not print this expecting it to hold up like real aluminum extrusion. Plastic has way too much flex. This model is basically for prototyping and testing if this type/size of extrusion will work with your project.
