The design by MishaT is amazing, fascinating and intriguing but it didn't take long for the pi to snap on two of the prints which I had made of this thing despite me printing out the latest veion of the connecting bar, V2. Thinking about it, the pi are a weak point because they rely on the plastic 'weld' of quite a small surface area layer to the one below it in order to provide strength. Saying that, I did manage one print using V2 of the curved connector which is still holding together well. This remix is designed to strengthen the parts which hold the whole structure together and uses an M3 nylon (or metal) nut and bolt to do the job.
