Proton Pack Upgrade/Replacement for Kenner Figures (Patreon)

This week's toy release is my own custom design for the proton pack accessory for vintage Kenner Ghostbusters figures. Only a handful of the original packs survived from my childhood - some missing the plastic stream, some with broken 'arm grips', some with busted back pegs. I wanted to give my old toys some new life with this 3D printable proton pack upgrade and correct a few of the 'design flaws' that are apparent in the original toys.

First - I wanted this pack to be based on the proton pack as it appeared in the cartoon series. If you have a close eye for detail, you'll notice that the original Kenner packs are different design from the cartoon and seem to be based on the 'pilot' animation! This 3D printed pack part is based on the design you see in the cartoon.

Second - I wanted the stream to be removable. The plastic beam in the original toys could not be removed and were subject to breaking. Most annoying - you couldn't safely store them in a toy bin and they wouldn't fit in the Ecto-1 or Firehouse! This design has an open hole in the blaster that can easily receive a 1.75 mm beam. (I simply tool some translucent PLA and bent it to a beam shape with a heat gun!)

Third - The original Kenner blaster was mounted 'upside' down in the original toys to accommodate the beam. Here, I wanted them to be mounted the 'correct' way with the hose/rear facing up like the move and cartoon. The blaster is mostly the same as the Kenner toy but there is some custom detailing on the part.

Fourth - The cartoon pack has a ghost trap! I thought it would be cool to design in a figure-size ghost trap that could plug into the other side of the pack. It is designed to be removeable like in the cartoon.

The parts shown in these photos were printed with a 'silk metallic blue' PLA filament by CC3D my like my full-size proton pack prop. I used and Ender 3 to make my parts using a 'fine' print setting in Cura as follows:

• Parts were "vertically" oriented on the bed
• 0.12mm layer height
• 205 degree c nozzle  heat
• 60 degree c bed heat
• Tree supports (these are great and easily break away from the small part)

To finish the part, I used 22 awg yellow coated wire to attach the pack to the blaster!
