Slot the 20mm bases into the upper frame and it locks them in place without any wobble. The MDF is nice and sturdy, so I’m confident it’ll last through plenty of games. Exactly what I needed for moving my skirmish units in ranked formation.

The 20mm round bases lock into this frame perfectly, no wobble at all. I was worried about magnets not sticking to the MDF base, but they work fine and the extra height option is great for unit cohesion.

The two-piece design is a lifesaver—the upper frame locks my 20mm bases in snugly while the lower base keeps everything flat on the table. Took about ten minutes to glue together, and now my ranked units slide across the board without a single model tipping over.
