I could make metal bars without trouble, but they defeat the purpose of the new knives if they hurt people by being angular metal, so I wanted to protect the corners, even if they were round. On paper, I sketched a design to cover the forward edges of the bars.
Instead of making the backside square, I made a flat-top cone with a cavity for the rounded bar. Even though I didn't make the end of the bar, a perfect semi-circle, the guard fit neatly, and the plastic came flush with the bar.
The first print was too large for the knife blade, so I shrunk the base of the cone, expanded the hole in the middle so it would fit a hexagon spacer.
The models printed in less than an hour, and I could test the second iteration without delay. There was a small gap between the blade and guard that I didn't like, but it would protect the user and anyone else in the ring.

Sketch for model
Instead of making the backside square, I made a flat-top cone with a cavity for the rounded bar. Even though I didn't make the end of the bar, a perfect semi-circle, the guard fit neatly, and the plastic came flush with the bar.
First print
The first print was too large for the knife blade, so I shrunk the base of the cone, expanded the hole in the middle so it would fit a hexagon spacer.
Changes for the second Rev
The models printed in less than an hour, and I could test the second iteration without delay. There was a small gap between the blade and guard that I didn't like, but it would protect the user and anyone else in the ring.
