It's prom season!
My tuxedo shirt studs and cuff links were delivered from Amazon in a not-so-useful tiny cloth bag. I designed and printed this handy holder that is much less likely to be lost, and will protect the studs from scratching.
It looks cool enough to hang on my wall!
The holder has 3 parts: two trays that sandwich the jewelry, and an outer sleeve. The longest part is 12 cm long.
I added hugger-fins to the inner trays in my second version. The hugger-fins make it much more rugged.
