Sneaker Spurs!

thingiverse

These are spurs.. for your sneakers! You can use these to keep other pedestrians from passing you, accent your belt buckle, or to train your dog! Instructions Glue 2 of the spikey things together, you should have 2 in the end. I used 3mm filament melted on each end to hold them in place. I used velcro to hold them onto my shoe. There are also slots where you can put tape, or a strap of some kind.
