I've seen many people walking around with beads on their shoelaces, so why not make it cooler?  

I don't know how practical it is once you start building on it (I haven't printed it yet) but I'm sure the possibilities are endless. Maybe these stringable bricks would also be useful for hoodies, illegal builds, or science projects. 

I made two styles: 

• 2x4 - just a normal 2x4 brick with a hole in the middle. Clutch power included.

• 1x4 - extra stabilization and a hole in the middle. No clutch power. 

I intended for these to go onto the lacing close to the toe, and different laces might be too thick to cross through. You could also thread them on the individual laces, sort of like aglets. Maybe you could use the 2x4's on laces with knots at the ends as a no-tie system. Again, the possibilities are endless :D
