This is a downloadable pack of STL files for home 3D printing; no physical bases are manufactured or shipped. Open Basing System CORE 1.0 provides a broad library of modular miniature bases, flying supports and display plinths for printing on your own machine. The pack covers conventional ranked and skirmish shapes alongside specialist hollow, reinforced and flying designs, with sizes extending from small individual bases to large scenic footprints. Files become available to download after purchase. Includes 745 designs across round, square, rectangle, oval, pill, hexagon, octagon, triangle, and flying base and stem families. Depending on the shape, designs include plain, hollow, slotted, reinforced, flying and wide-lip bases. Hollow bases can hold resin, allowing a miniature to appear as though it is standing in water or another liquid. Flying bases use a 3 mm stem hole. Flat-foot and tapered stems cover 20–80 mm, with larger cruciform and curved ball-top stems also included. Type A stepped display bases are supplied in oval, round, rectangle and square formats. Print the files on your own 3D printer using your chosen material. The Regular Licence covers personal, non-commercial printing; the Commercial Licence permits selling prints and includes OBS reseller permission. Both include one year of download access and free updates, renewed by repurchasing. Compatible with popular tabletop miniatures; not affiliated with, endorsed by or produced by Games Workshop.
