Modular Sandbag Trenches STL Bundle

Build a connected battlefield with seven modular trench STL designs: Straight, Wide Straight, 45° Corner, 90° Corner, T Junction, Cross Junction and Zigzag. Includes an assembly guide and personal-use license. Sculpted sandbag walls, weathered timber floors and textured earth banks are designed for 28–32 mm tabletop games including Trench Crusade.

Optional magnetization uses 6 mm diameter × 2 mm thick magnets, with two pockets per connection end. Straight, Wide Straight, either Corner and Zigzag use four magnets per piece; T Junction uses six; Cross Junction uses eight. Magnets are purchased separately. Match polarity before gluing.

STL coordinates are in millimeters. Print at 100% scale to preserve magnet compatibility. Designed for FDM with the flat underside on the build plate; inspect your slicer and confirm magnet fit before batch printing.

Digital download only. No physical terrain, miniatures, paint or hardware is supplied. Personal use only: do not share, upload, redistribute or resell the files, including modified versions, or sell prints made from them. Contact Hangar81 about commercial licensing. Independent terrain; not an official or endorsed Trench Crusade product.
