This was designed for DIY purpose, allowing for those who are handy to start using common water pipes and easy to find pipe connectors to set up the frame. To make it even easier to do, we have a design that there is no curvature at all. The top consists of four 4-meter pipes forming a real pyramid using a 6-way connector. Coming down from the top, we suggest that you use four 45 degree elbows to extend the top pipes down into the ground using four more 4-meter pipes. This forms a straight edge and surface structure as shown below:
