Hero Round Base Adapters
This set consists of sixteen HDF adapters for single models: 5x from 25 mm round to 25x25 mm square base, 5x from 25 mm round to 30x30 mm square base, 3x from 40 mm round to 40x40 mm square base, and 3x from 40 mm round to 50x50 mm square base.
Manufacturer: Tabletop Scenics
Each adapter consists of a base (HDF 1.5 mm thick) and a frame (HDF 3 mm thick).
The parts have to be glued together before use.
HDF bases are the most inexpensive way to quickly set your numerous models on their feet (or re-base if that rules update hit you out of nowhere). Precise laser cut ensures that the base will always keep the correct size.
