Place a miniature on its square base into one of these converters and it occupies a rectangular footprint — no rebasing, no glue, no magnets, nothing removed from the model. It lifts out again just as easily, so one collection can play a rank-and-flank system such as Kings of War and go back to its square-based game afterwards. Sizes run from 20mm square up to 150×100mm, 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 square base sits in a recess and holds by friction fit, and an open underside lets the base be pushed out without gripping the model.
Removable and reusable — one collection serves both square-based and rectangle-based games.
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.
