Completely customizable collar stays!! No more using and losing flimsy generic stays. Monogram with your initials, name, or image/logo. Show off your tech/geek cred while remaining stylish! I initially set out to learn Openscad and recreate my collar stays originally designed in Tinkercad (now defunct). Soon I realized how easy it was to use Openscad and it all spiraled out of control. Pretty much every part of this design is customizable. You can add relief or embossed text or images. Adjust the sizing to get the perfect fit for your shirts. Seriously, get rid of your old collar stays and start using your own personalized ones. They can also be adjusted to become tags, bookmarks, herb/plant markers, and more.
