As we work eventually towards the Yawning Portal, one thing we need are railings. This set doesn't follow established open lock tile layouts, but it's a very specific use case. Further, since these need to hang in the air, for now at least I have not bothered with magnetic versions - these really need clips.
I struggled a little with MMF tonight, so for now, the files are attached here and in the openforge sync folder, and I'll get them up on MMF tomorrow.
