Sideburn's "Invaders! (v2)" made to turn your average shoelace into a bolo tie. Four different Invaders to choose from. Print two of the missile "pulls"; they are designed to fit 3mm aglets, since that was the average of my various shoelaces, and you will want to glue slide the lace-tips in with just a drop of glue. I'm going to leave this set as "in progress" for now since I'm concerned that even if Sideburn's pixel designs hold up on the thin joints in the short term, I want to make sure they can survive a week or so of actual use.
