penta sphericon plate

Just fiddling with Fusion 360, having watched Maker's Muse and Make Anything play with these things. Two pentagonal halves with concave sides and a pentagonal peg to hold them together. The peg allows you to align the halves straight up (doesn't role but is kinda neat looking) or at an angled offset for sphericon madness. As designed the resulting sphericon is about 35mm wide. Scale it up or down as you like.
