The print works perfect. I would suggest maybe adding some instructions in the description to enplane how the knob if fitted inside correctly as i did it wrong at first was only after taking a closer look i seen how it works. i know others will make that mistake and not spot it. then will think its not a good design when it is. Other than that top marks.

Works great for mounting my phone to a tripod. I added a print profile.

Amazing! No hardware required!

This is why I love 3D printing!

Came out great but I wish there were assembly instructions, speciafically what to use for a pin on the screw head.
