Compact Build without sliding hinge

Created this to solve a problem I had: the sliding hinges kept breaking free from the build plate during printing. They have a small footprint, and it takes very little force to knock them loose. Even just the nozzle putting down another layer can be enough, in my case. Changing the print orientation so they have a larger, more stable contact area isn't a good option, as (because of the change in direction of layer lines) weak points would be created right where they're under the most stress dur
