Update: 

The Flat_Face version is easier to print. The original version requires more supports.

 

Recommended print settings:

  • Material:  PETG
  • Layer Height: 0.15 mm or less
  • Infill % : 50+
  • Supports:Yes, Organic/Tree
  • Print Orientation: Default as modeled

 

Postprocessing:

The rotating latch may need to be “broken loose” the first time. After printing, remove any support material, and place the latch in a vice. Using pliers or a screwdriver, rotate the latch. I added some graphite powder to lubricate the inside as well.

 

There appears to be several variations of the Trunki suitcase, each with a slightly different latch - not just different colors, but a different mechanical design.

 

I modeled this latch off of one that looks like this (no hinge):

 

Other variants that are not be the same:

Metal Hinge:

 

Plastic Hinge

 

 

This design went through several iterations - a few examples, not all of them were successful prints:
