This is another rush week, meaning both solutions were made in a few hours, so neither are particularly optimized. My only goal for this puzzle was to get the bestagon, and unless I missed something (which is very possible), I believe I did.

If radius 3 is possible, please skip the rest of this message, but my cell calculation was 4 + 2 inputs, 7 outputs, 2 bonder, 2 debonder, and 2 projection equaling 19, leaving no space for arms in a radius 3 solution. 

To be honest, I would have preferred if 3 radius was possible, but extremely difficult. I generally dislike period puzzles, so once I got a decent solution with radius 4, I submitted it, so I don't expect to place particularly well
