Round to Square Bases Shape and Size Converters 3d Print Full Range
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.
