The files I posted match the size of the original that I remixed. If you wish to replicate my keychain's size, scale the files to 80%.

Scaling to 80% allowed me to fit 5x2 mm magnets in the print. However, you may want to use a taller magnet for the one that goes in the trap cartridge. This allows for the cartridge to be removed similar to the movies and then magnetically re-attached. 

Supports may not be necessary, but I used organic supports to ensure decent quality.

Post-Printing

I utilized metallic and white paint pens to highlight some of the model's details, and to give it a weathered look. I simply used a black Sharpie to add the black caution stripes to the trap's lid.
