Those are beautiful! Could you make money selling them?
A question - there seems to be a lot more to this height adjustment than is obvious. What are the details?
The iron red one is one of the 100 customized ones I found in the factory, and the thread is very poor, and the concentricity is also very poor, which makes me lose confidence. So I had to make my own screws and nuts. Then use standard mechanical screws to lock.This is the original design, I have changed some sizes according to my own aesthetic direction, but my knurled is not clear enough. The structure is very simple, the internal is M16*2 metric thread.
