This is a replacement base plate for the "Samsonite 1910" aluminum logo located at the top of the Cosmolite Spinner series (first generation ?) suitcase. After years of use, I noticed that the original had become sticky, brittle, and eventually broke.
To replace it, you'll need to remove the two rivets from inside the suitcase using a plastic or metal pry tool, such as the ones commonly used to open smartphones.
I printed mine in PETG with 100% infill.
(Please note this is the base only, not the aluminum part.)
