Ecto Containment Unit - Part 1 - Main Case
🕑 Added 2025-09-13 19:50:04 +0000 UTCThis post contains 10 3D printable modules for building the main case of the Ecto Containment Unit.
May I PLEASE see the storage facility?
This past winter, I published a Containment Unit interface for inserting a trap. I thought it would make for a nice standalone display piece even if I never built a full ECU. I've seen a number of builds pop-up that have been integrating these parts (notably the cartridge clip for the Haslab trap). With my Halloween preparations well underway, I thought it was time to finish what I started and make a fully 3D printed Ecto Containment Unit.
These files are for the 'Main Case' compatible with the interface design. It is 10 sections. The assembly tips I have are very straight forward:
Make sure you stock up on red filament if you intend to use filament colors. (this is how I did mine. I used matte red from Polyterra. I went through just under 8 rolls total for the ENTIRE finished project…).
The parts are designed to simply glue together. For test fitting, I used a collection of small and medium binder clips to clamp everything together. (In fact, the solution has worked so well, I haven't yet permanently glued my parts together!)
Part 2 coming soon...

I am still unsure what the purpose of these holes are for?

What are all the screw holes for on the bottom sections (H, G, F) for behind the hinge holes?

Moby’s Sign Company on Etsy has Ecto Containment Unit label sheets. They are very well done.

Do you know any print shops that will do a small batch of the stickers (maybe 5 to 10 of each sticker)? Or, did you find all of these online somewhere?
