Drop a miniature on its oval base into one of these converters and it occupies a larger oval footprint — no rebasing, no glue, no magnets, nothing removed from the model, and the base lifts out again when the original is wanted back. Sizes run from 50×25 mm up to 170×105 mm ovals, including the one shape change: a 50×25 mm pill base into a 60×35 mm oval. 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 work with the Open Basing System’s own bases, movement trays and other converters.
No glue, magnets or rebasing — the oval base drops into a 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.
Works with Open Basing System bases, movement trays and other converters.
