This is a replacement part for a set of suitcases I own. The button to raise and lower the telescoping handle broke on two of the three suitcases in this set. My set of suitcases was branded Pierre Cardin but I am sure the design is not unique.I printed the replacement parts with 100% fill.  I also enabled support.  Not much support material is needed because the overhang is so close to the build platform.
