Proton Pack Centre Cover

UPDATE 2/12/17. This part was used in the Ghostbusters Station 6 fan film. Check it out on youtube at https://www.youtube.com/watch?v=RHMUsQqLmRg

A full size, 3D printable version of the Ghostbusters' proton pack centre cover.
Based on Steffan Otto's plans at:

Print 2x CentreTubeMount.stl.
Join parts together with 3/8 #4 screws. Lower tube needs to be
fastened to motherboard with #4x 3/4 screws.
Print CentreDrill.pdf at 'actual size' for motherboard drill centres.
I used Big Boy plastic filler to blur the junction between parts 4 and 5.

UPDATE 24/11/14: Some people like the tube on the raised section
to be the same length (and therefore higher) than the lower tube.
Print CoverTubeTaller.stl instead of CentreTubeUpper.stl if this
is how you want it.
