On our trip to congress, the button on our suitcase broke. Luckily it happened at Hamburg Central station and most of the way left i had to lift the suitcase anyways.
At home i looked int replacement parts, but they made that pretty hard, so i just designed my own and printed it.
I had to make a few prototypes to get the dimensions just right.
