Hammer K3 slider T-nuts?

[Cary Falk]

They sound easy enough to make if I am understanding correctly. A wedge of sorts with a tapped hold. I could 3d print them, but I don't think I would trust the strength. I could probably mill them on my CNC pretty easily. If nobody can find a solution and there is enough interest, I might give it a go.

Seeing Erik's post, 3d printed with a heilcoil sounds simple enough.
