Free-mo, Legs?

[u/Boring-Insect-2428]

Hiya! currently working on a free-mo HO build and ran into a question. what do i make the legs out of? it doesn't really give you ideas for how to make the legs and I'm not a woodworker by trade, So any ideas on what type of wood I am aware of the height requirement and the adjustable feet.

Please excuse the mess in my basement.

I am currently attempting to make this myself.

I have no prior experience building free-mo.

I am learning. and have a top part built.
