Hills for DBA rules

Modular hills for use with DBA rules.

Good Hills & Difficult Hills.

Fit inside a rectangle of 3 BW x 5 BW […the length plus width totals no more than 9 BW]. Extra middle sections allow longer hills to be made if required.

Hills have a clearly defined ridgeline.

The maximum height of the hills is 16 mm [based on a 40 mm BW] so that a gentle slope prevents the base from toppling or slipping.
