Bottom exit remix -- Python AMS enclosure

The Python AMS enclosure is HUGE. Workbench space is too valuable, so I chose to mount the enclosure on the wall, requiring a bottom exit for the AMS cable and PTFE tube. I edited the original (v1.03b) STL files to fill in the existing holes, add material to the bottom surface, place the 8 threaded holes, and moved the back dovetail forward about 6 cm so the lateral screw hole is accessible. In my version, only the two holes closest to the center are opened up to allow the AMS cable to pass through. This is because the AMS cable can bend on a reasonably tight radius. I suggest using the outer holes for PTFE tube(s) where you can achieve a large, smooth radius. Another design feature is that the holes are sufficiently spaced from the back edge so that the 14mm screw fittings can be inside the box. Of course you'll need to drill holes in the bottom panel of the enclosure, but only for the through holes you'll actually use. I used a ¾" Forstner bit in a hand held drill, went slowly, and h
