How to build an adjustable height monitor stand?

How do I build a monitor stand with height adjustable legs. I’ve searched everywhere for one that will be long enough to fit dual monitor screens - 56cm each. I also would like a 50cm gap between the legs so my keyboard can fit underneath.

Hi @evo75,

Those feet are 100mm high.

What about installing 25mm x M8 Round Threaded Inserts in the bottom of the timber and using 40mm x M8 Ball Jointed Levelling Feet?
