@mntmn Yes and no. 😅
Initial project introduction is at https://phryk.net/article/introducing-fort/
Project repo is at https://rnd.phryk.net/phryk-evil-mad-sciences-llc/FORT but not very helpful right now.
Currently only contains the already publicly available THAM12 design as OpenSCAD model with 45° bevels for more robust connection between the pieces, but with the reinforcement pieces still missing.
Also the prototype I built doesn't even use the 45° bevels because I currently don't have the necessary tooling for that.
