I used metal prats at my previous design, some pictures and videos are directly from that.
I used that for reference. It's the same way to install them.
If you want a metal bolts version, please let me know.
This model is a stand for portable monitors with vesa mount.
I used a new design so you can adjust the angle and height easily.
You can change the needing force just by tightening the bolt.
I am not very good at English. If you find something confusing, please leave a comment so I can fix it.
