4 questions for OpenLOCK City Foundations Pack

  1. Alexander Breaux (verified owner)

    This may be a silly question but is the intent for these to stack the floor on top of some other risers behind each wall? I thought there would be a set of riser pieces in the set but I don’t see them. What did you all do for this in the photos?

    • Joanne Boorer (verified owner)

      Hi. Thanks for your query. We used Styrofoam to build the set to the height we required and then place them on that.

  2. Luke Everall (verified owner)

    I had a similar question as well – how do the raised floors connect to the wall tops? I can only think the intention is to glue them.

    Like the above poster, some form of scaffold structure is required to keep everything in place, or are we using foamboard or other means to build our own structure?

    Currently printing some of these pieces for a set up of a city. Loving the design and how they work. Only had a few things I was wondering about.

    For I-Column-Buttress-CFB : the bottom of this that is connecting to the base print plate is not flat like the rest but curbs in, Is there a reason for this?

    Also love that you included the Flat designs for the High walls, only problem I had is that they are to high for the hight differences I had. Any chance you also plan to release a flat version of the 2inch high walls ? And perhaps a 2 inch version of the foundation Grate and Arch? could help a lot with modular building plans.

    I`ll upload some images once i`m done with planning with my printed test pieces 😀
    Great Job!

    I’ve also found a problem with I-Column-Buttress-CFB, it doesn’t sit flush to the build plate, it takes about 8 layers for the “base” to appear

    • Matt Barker

      Ok thanks for pointing that out, I’ll fix that right away.
