Ghostbusters Ghost Trap (1984)

First released in 2016!

OCT 2026 UPDATE

My sincere apologies to anyone who has downloaded these files since I posted them here in Jan 2026. I originally included an ARCHIVE.zip of old parts for those who might need them. I did not realize Printables automatically unpacks any uploaded ZIPs - so all the old parts were mixed with the new creating a horrible mess! This has been fixed and the Print Guide PDF has been updated as well.

PARTS Assembly hardware, greeblies, labels and Electronics Guide are available in my shop - https://charlesworthdynamics.etsy.com

ASSEMBLY GUIDES All assembly guides other than Electronics Guide is available for free on my site. http://bit.ly/3D_Kit_Instructions

Electronics Guide can be purchased from my shop: https://charlesworthdynamics.etsy.com

ASSEMBLY HARDWARE A complete list of hardware needed for a Standard trap (fully 3D printed) is included in the Print Guide. You can also get all hardware and Deluxe (as much real hardware as possible) upgrade parts directly from me: https://charlesworthdynamics.etsy.com

Trap Pedal is also available to print:

See my Profile for social links, where I do most update and new item announcements.

This Ghost Trap is over 55 parts designed to be fully 3D printed except for the screws that hold it all together. The trap can also accommodate electronics for lights, sound, door mechanics and smoke. The first two pictures show a Deluxe trap with as much real hardware as possible.

This is a hybrid between the GB1 & GB2 traps - overall size is GB2, the protruding cartridge is GB1.

While the trap is fully printable, it was designed based on real parts whenever possible so they can be swapped out as an upgrade. For example, 1/16" aluminum plates can be swapped out by using the 3D printed ones as a template.

To learn more about how the Trap was designed and built, see me on Tested.com:

Print Settings

Notes:

You will need a print bed that can accommodate up to 8.8" x 4" (224mm x 102mm) for longer parts, like the bottom and side plates, I have provided cut versions for smaller print beds - you will still need at least 7.3" L x 4" W (186mm x 102mm).

If you built a Trap before Feb 2022 and need to reprint something see Trap Parts ARCHIVE.zip.

All files have been run through mesh repair and are ready to print. They are oriented for optimal print quality.

To help confirm scale, I have uploaded cube_1_inch.stl and cube_20mm.stl. Load one of these cubes with the parts and confirm if it is 1" or 20mm. If so, all the parts should be at proper scale.

I'm not providing print settings since it can vary wildly from printer to printer. Certain parts, such as the handle and handle frame should use a higher infill for strength. Other parts, such as the foster connectors benefit from slower speeds. A hardware list and print guidelines are included in the download.
