These flat 3D-printed trays let a model remain on its existing square or rectangular base while occupying a larger ranked footprint. Each part works as both a movement tray and a base-size converter, with a closed floor and seats cut slightly oversize so the original bases can be dropped into place. Options cover 20 mm square to 25 mm square, 25 mm square to 30 mm square, and 50 × 25 mm cavalry bases to 60 × 30 mm. Grid options are named bases across × lines deep, so 4x3 holds four models wide in three ranks.
The 20 to 25 mm range includes 28 grids and the 25 to 30 mm range 31, both starting at 2x1 and running up to 8 bases across or 6 ranks deep.
The 50 × 25 to 60 × 30 mm range includes 16 options: grids from 2x1 to 6x3, plus stepped Lance 3 and Lance 6 formations.
Overall sizes run from 54 × 29 mm to 244 mm across and 184 mm deep, with tray heights between 4.5 and 5 mm depending on the format.
Black PLA, 3D printed to order. Fine layer lines and a Z-seam are normal on a printed part, not defects, and disappear under primer.
Part of the OBS (Open Basing System) range. Nearly every option includes its own technical drawing on the listing.
Suitable for Kings of War, The 9th Age and other rank-and-file or historical ranked play. Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.
