    Will there be a bridge converter for a straight wall section?

      Yes this is something we could look at doing.

    Hi, couple of errors on the assembly guide I’ve spotted

    Square Tower Level 1
    Parts List state rustic wooden floors but they’re stone in the diagram
    Buttress quantities are switched. Should be 4 off #8 and 2 off #9

    Also on the round tower ground & first floor stairs it really bugs be that the stair floor is wood at the bottom but the rest of the floor is stone. Any chance of a Stairs with a stone floor maybe? if their isn’t one already.

      Thanks for that, we will get that updated. We are working on a stone floor version of the spiral stairs.

    Hello! I’m new to the Openlock/Rampage modular pieces.

    If I wanted to print and build just the exterior of larger Clorehaven buildings, I’m guessing I could just skip the floor pieces and staircases? If I’m willing to just use CA glue perhaps?

    The assembly would seemingly be more precarious, but would the finished hollow building be too fragile to be worth the time and PLA saved by skipping the interior pieces? Thanks!

      Floor pieces really help with keeping the buildings rigid. You can probably skip the stairs, but I would definitely print the floors to give that cross bracing support if you want to glue. Plus the floors don’t really take too much time to print.
