I have a job interview coming up in a few days and I can never find a tie clip when I need one. Instead of investing a over 10 dollars for something I'll probably loose, I instead spent about 20 minutes with tinkercad and came up with this.
Instead of holes, you could go with a different type of negative space design, I just wanted something simple that would give me a decent print.
There are support struts on the back of the clip to loop a shirt button through so the entire thing stays in place.
It only takes a minute or two to clean up with slight sanding here and there.
