As we mentioned earlier, we're getting the make-up release out for the week we missed earlier in December. This time around, we have released the full array of OpenLOCK rectangular half-height walls as well as all of the rectangular floor segments in half-height sizes.
I've had a lot of requests lately for the half-height walls, as they solve some of the problems that DM Scotty's TileScapes fix (not blocking the view). However, even for GMs who like using the full-height walls, these have tons of uses as low walls, fences, etc.
The half-height floors are very useful as well , giving you the flexibility to build out daises, raised platforms, or just varying elevations.
Grab 'em both on Thingiverse and let us know what you think in the comments below.
