Proton Pack Thrower Banjo
thingiverse
Update: April 21, 2016. Single screw and banjo STL files now available. A full-scale, 3D printable replica of the crucial Legris banjo and screw used in the Ghostbusters' proton pack thrower is now possible. The component shown was printed from ABS plastic before being treated with acetone vapor to smoothen its sides. A coat of paint was then applied to give it a convincing brass-like finish. For step-by-step instructions on how to achieve this look, check out my earlier post at: http://funwithelectrons.blogspot.co.uk/2015/01/making-parts-look-right.html
