I found this lovely example of my XYZmbe design folded by Michal Pikula. It was a planar module named in honour of Sam Evison, a delightful man who used to run the Hazel Grove mini-meetings in the 80s when I was a regular attendee. He was awarded an MBE for services to children. I created a series of diagrams for simple models in the BOS magazine for a column in his honour.
