Drop a miniature on its round base into one of these converters and it occupies a square footprint — no rebasing, no glue, no magnets, nothing removed from the model. It lifts out again just as easily, so one collection can move to a rank-and-flank system such as Kings of War and go back to its round-based game afterwards. Sizes run from 20mm round up to 100mm square, and each converter is 3D-printed to order in black PLA in the UK; we usually keep some stock, but we may need a while to process your order. The converters stack with the Open Basing System’s own bases, trays and other converters.
No glue, magnets or rebasing — the round base sits in a socket and holds by friction fit, and an open underside lets the base be pushed out from below without gripping the model; where the square is barely larger than the round base, the converter is a four-corner clip that grips the base at the corners instead.
The base’s top edge sits flush with the converter, so the model is not raised.
Textured top surface matches the rest of the range, and PLA takes primer and acrylics, so the converter can be finished to match existing basing.
3D-printed black PLA, made to order in the UK — fine layer lines and a Z-seam are normal, not defects, and become less visible under primer.
Works with Open Basing System bases, movement trays and other converters.
