Dart Training Target Hexes

I saw a video on YouTube referencing a similar set of these. I searched for about an hour, and could not find a set to buy, so I hopped on TinkerCAD and modeled a set for myself. I figured others might like to use them as well, so I'm sharing it here. The holes on the sides are for pins to hold them to the board. They are approximately 55mm for the large one, 45 mm for the medium, and 35 for the small one. The triple space on a steel tip dart board is approximately 33 mm across the outer edge.

I haven't printed them yet, but plan to use 0.2 - 0.3 resolution, 100% infil, and I'll likely use a flexible filament when I do. The ones from the video were flexible, and I can easily see steel tip darts breaking a hard plastic.

Constructive criticism is welcome, as this is my first upload to Thingiverse. Thanks, and enjoy!
