One of them alone can stand its own ground! These are among the most phenomenal prop builds I have seen in my many years of collecting. Just to compare the raw vacuform shells with the finished product is a startling contrast. It is unbelievable to me how much creative planning and fabrication went into building these, and the use of so many different types of media and techniques on everything from the spring hinge system to the 3D printed fixturing pieces are truly ingenious. I think its nice that Scott documents his builds so well and provides the print files for everyone on here in the true spirit of this forum, but this is certainly a build that takes some incredible skill that few people I know could pull off.
