Belt Tensioner Knob

When I got both X and Y belt tensioners for my Ender 3 Pro, I was really disappointed. Each tensioner had a different knob. So I decided to take the one I liked the most and create a model for it.

Prints good enough without supports on my setup. I used higher infill to give the knob more mass. One threaded insert is needed for M4 screw, designed for M4x8x6 (8mm tall) one.

On the pictures the original knob is the black one compared with my 3D printed one in gold color.
