Ghostbusters Hasbro Proton Pack Cyclotron Inserts

These are a friction fit, press in mod that requires no permanent modifications to your 1984 hasbro proton pack. They can be a tight fit, so use caution. These files were created using reference from https://www.theghostbustersreferencelibrary.com/ and  https://www.gbfans.com  and every measurement I sued was taken directly off my my personal hasbro 1984 pack. These were designed to mimic the cyclotron rings as seen on the 1984 proton packs. I used the Spengler pack mostly as reference. This is a non invasive mod, which means it can be reversible if wanted.  

Enjoy!
