Warhammer Realm of Battle board connectors

Improved connectors for Warhammer Realm of Battle boards.

I bought a RoB board but the connectors are fairly hard to position right, these connectors make it much easier to assemble the boards.

A full set consists of:

- 2x Middle (Cross)
- 6x Edge (T)

But you could possible get away with just the 2 middle cross pieces.

I printed mine at 0.3mm, 15% infill using PLA.
