Curved/irregular Warmaster Revolution dense terrain base

This is inspired by https://www.thingiverse.com/thing:6694273 , but with curved/irregular shapes rather than rectangles.

The base has a removable section for use as dense terrain, such as built up areas and woods. Decorate the removable insert with terrain, then remove it whenever a unit enters the terrain feature.

The frame is exactly 2cm wide and the rounded corners have a radius of 2cm. This means that any unit standing inside the frame with no part of the base on the frame is out of line of sight.

The chamfer on the outside of the frame is exactly 1cm wide. This helps with checking visibility, although after painting and decorating it may well no longer be visible.

There's also a version with a 0.5cm wide border, in case you don't need it for the terrain rules, and solid versions (no removable insert) if you just want to decorate the shapes.

For speed, I printed with a 0.8mm nozzle and 0.4mm layer size.
