The two-piece design makes swapping the upper frame for a taller one a breeze, so I can adapt the same base to different model heights. Everything sits flush and moves as one block on the table, no wobble.

The MDF frames fit perfectly on my 20mm round bases, and the two-part design makes assembly quick. I’ve been using them for my rank-and-file units, and the height options let me match different base thicknesses without any wobble.

Finally, a conversion tray that actually fits my 20mm round bases without any wobble; the 3mm MDF frame is sturdy and holds everything in place during a game. The separate base and frame design makes it easy to swap different heights depending on the unit.
