Klöts (Quick shoe ties) remixed for no sanding fit.

UPDATE (17 Nov 2015): As much as I love these, after a couple of runs with them on my running shoes, I'm sad to report that they have started to unlatch themselves in the midst of a run. :( So I do not recommend these for use in any sports activity. It has been a short-lived love affair for me with these klots. The concept itself is a great idea, but the design doesn't quite stand up to more rugged use. A different method of locking the pieces together with no chance of coming apart during use is what's needed. i've stopped using them now. But the good news is, I've come up with a different design altogether which is more secure and just as easy to put on. Right now I'm still testing it and may refined the design further, but I am very confident with the fastening that it achieves. Stay tuned... UPDATE (20 December): My design is finally released! http://www.thingiverse.com/thing:1213127: Print Settings Rafts: Doesn't Matter Supports: No Resolution: Ulttra Low quality with M3D slicer Infill: Not necessary with thick walls
