This design really caught my attention! I was so enthused I built the frame already from your posted drawing. I am doing this from scratch but I work in a shop where I can salvage enough material to work on building one. We have an industrial 3d printer so I may be able to con an engineer into helping me print some parts.( unless I can machine some) The problem is I just started and don't have a clue yet about what I need besides the files you have on this page. Any advice for a noob who never built one before? Like a list of the parts needed from the original Mendel?
