UPDATE 23/10/22: Specific details for WallBooster specified. UPDATE 2/8/18: This component is used in Ghostbusters Station 6 fan film and can be seen at https://www.youtube.com/watch?v=MZ5T9jS1lM0 A complete gearbox, fully 3D-printable, is designed specifically for the Proton Pack based on Stefan Otto's plans found at http://gbfans.com/wiki/Stefan_Otto%27s_Prop_Plans There are other versions of this design, but they use an excessive amount of plastic as the entire body must be completely filled. Also, the rounded 'gear housing' at the top is printed perpendicular to the radius axis to achieve a smoother finish. Print gearbox.pdf in actual size for accurate details and centers of drills needed to attach it to the motherboard. Six #4 screws should be used to fasten it. The top part is attached to the bottom using four #4 x 5/8" self-tapping screws or epoxy glue. Print GearboxGearHousing at 100% infill for added strength when attaching a ribbed tube. A wall booster should be printed inside the gearbox to reinforce the gearbox's wall where HGA attaches. Epoxy glue is used to fasten GearboxgearHousing to GearBoxTop. Some sanding may be required to help it fit correctly. UPDATE 3/2/16: Gearbox bottom walls have been thickened by 3mm. Anyone who downloaded before this date should print and glue wallbooster.stl for reinforced HGA attachment wall. UPDATE 1/12/15: The hole used to attach the HGA has been raised slightly to prevent HGA fouling on motherboard corners (http://thingiverse.com/thing:652812). UPDATE 8/1/16: Inverted GearboxBottom due to printing limitations. UPDATE 2/3/16: Additional details have been added to the top of gearbox.
