This is my version of the Ghostbusters ghost trap from the movie Ghostbusters. It was built using TinkerCad and is fully detailed right down to the weld marks! The Cartridge is removable from the outer frame, the trap doors can open and close and there is even a working cartridge catch switch that holds the cartridge in the outer frame and releases it when the handle switch is slid forward. This trap is actual size. The design is based on a combination of "Sean's Ghost Trap Plans" from the Ghostbusters fan site" and photo reference of the "hero" trap from the same site. http://www.gbfans.com/equipment/plans/sean-bishop/#ghost-trap-plans http://www.gbfans.com/equipment/reference/12/ This was a work of love. Please print it out and enjoy it.
