Sorry, 1 more question. At what timeframe do you expect diy packages to be for sale? I have checked with steel manufactures before for other projects, but having a small batch of steel tubes means that they will be enormously expensive and the same goes for the PCB's. The milling I can do easily at a maker space (fablab013). I am planning on a rather long, 1 storey hive, so I plan to cut the metal tubes in half and mount an extension in between.

I'm I missing something, I can't find the folder "frame" in the design files. Also am I correct that end of the frame goes at the front and the other at the backend of the beehive? and the width (between the bars) is approx Dutch spaarkast size?
