openGrid với lỗ vít tương thích Multiboard

openGrid tiles with threaded holes that are compatible with Multiboard small threads (see GIF).

Why?

1. Easily attach models using just printed screws

2. Use screw-in Multiconnect points

3. Create models cross-compatible with Multiboard, just by adding elongated holes to your designs

I've included tiles 2x2 to 12x12, T-screws and Multiconnect points.

Note: I drew these threads in CAD. They aren't exactly the same as the original Multiboard threads, but after some trial and error they work quite well and should be compatible.
