These are the building bricks I have made. They actually do work I have printed them myself and they do go together. Just a warning slow down the printing speed or else they get sloppy and some will work and some won't. Be sure to check out my other designs and follow me for more designs and addons to those designs. And as and addition in order to not copy these bricks DO NOT work with other bricks. If I get enough complaints in the comments area I will make some that are to scale. And maybe some different types of pieces.
