So this is based off a pinterest picture I found, it's a shoe Kubaton. They sell for like $15 on Amazon, not sure if that's for one SET or one.
I've had this in my head since I originally saw it but simple simple design.
Anyways, work in progress, printing it now and printing the V2 also.
Designed in Tinkercad with over 30 sec of grueling blood sweat tears and blisters.
If you have any thoughts or suggestions, let me know, I recently have time to play with my printer again.
I'll probably go in and add some changes to it later, takes about an hour to print, I printed at 70% and 80% infill with 5 layers top and bottom.
I based these off my 5.11 8 Atac 2.0 side-zip boots.
Edit1:Probably going to add a fourth spike so it can be more secure at the bottom spike, but overall, these aren't going to come loose while walking or anything. I also didn't notice any pressure on the top of my foot. I'll probably widen the base just a bit to give it more stabilization.
