Finally, no more fiddling with individual round bases; these lock together solidly and the MDF is cut cleanly with no rough edges. I ordered the lower 3mm frame height and my models fit flush without looking clunky.

Picking the right height for your bases is key, and this MDF tray slid my 20mm round minis into perfect formation without any wobble. I've already used it twice for a dense ranked block, and the upper frame keeps everything aligned.

After gluing a few together, I'm impressed with how square and rigid the MDF frame sits on the base, and the lower lip grips the round bases tightly so nothing shifts mid-game. The 11x3 layout is exactly right for my infantry block, and the frame height option let me match my bases perfectly.
