Drop a miniature on its square base into one of these converters and it is held by friction on a larger square footprint — no glue, no rebasing, nothing removed from the model. The top edge sits flush, and an open underside lets you push the base out without gripping the model, so a finished, painted miniature can move up a size and go back again. That covers rules changes, unit re-roles, a D&D character stepping up a size, or a big model needing a steadier footprint. Sizes run from 20 mm squares up to 200 mm, and a base can usually move up one step or several — a 40 mm base can go to 50, 60, 70, 80 or 90 mm. 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.
No glue, magnets or rebasing — the square base sits in a square recess and holds by friction fit, and an open underside lets the base be pushed out from below without gripping the model
The base's top edge sits flush with the converter, so the model is not raised
Textured top surface 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
Part of the Open Basing System — converters, bases and movement trays in the range are designed around the same sizes
