Hyundai I30 floormat clamping nut

Hello there, last week my floormat became loose because the piece that was keeping it attached to the car's floor broke. Therefore, I modeled it out on Fusion 360.
It's not a 100% accurate, but gets the job done quite well.

I only had PLA, and it works well, but I suggest you to use ABS because of it's better mechanical properties
