Proton Pack Gearbox by tgoacher

Last crawled date: 3 years ago

UPDATE 19/7/2019: Specified position of WallBooster.
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, 3Dprintable gearbox for Ghostbuster Proton Pack based
on Steffan Otto's plans at:http://www.gbfans.com/wiki/Stefan_Otto%27s_Prop_Plans
There are other versions of this, but they are very wasteful of plastic as the entire body needs to be filled.
Also, the rounded 'gear housing' at the top is printed
orthogonally to
the radius axis to give a smoother finish.
Print the attached gearbox.pdf at 'Acutal Size' to get a plan of the
drill centres to mount it on the motherboard. Use six #4 screws to
fasten it.
Attach the top part to the bottom using four #4 x 5/8" self tappers, or use epoxy glue.
Print GearboxGearHousing with 100% infill for strength when
attaching ribbed tube.
Use the wall booster on the inside of the gearbox. This is to reinfirce the gearbox wall where the HGA attaches.
Use epoxy glue to fasten GearboxgearHousing to GearBoxTop. It will probably need slightly sanding to help it fit.
UPDATE: 23/10/14 Gearbox bottom walls thickened by 3mm. If you downloaded before this date, please print and glue wallbooster.stl to reinforce wall that mounts HGA.
UPDATE: 2/11/2014. The hole used to mount the HGA has been
raised slightly to prevent the HGA fouling the motherboard corner:http://www.thingiverse.com/thing:526108
UPDATE: 6/11/14. Inverted GearboxBottom as it was not printable.
UPDATE: 13/11/14. Added missing detail to the top of the gearbox.
