Check out my first cosplay product - a bit of Star Trek prop for a change http://shpws.me/Qznz
Scale_Stuff_ModelsHow strange, I made 3 off these from solid aluminium, I machined them with 9 fins since this is correct to the original prop from a drawing produced from this model. Spot the obvious error! I have updated the model as you will see on that page.
Working on some quatrefoil designs after buying a compass and ruler geometry book; really interesting how these are based on equilateral triangles and squares inside circles
