It looks like it doesn't take more than a 4x8 sheet of plywood. Could this be cut with an inexpensive router? If so, the materials and router would probably be like $40 + $80 = $120?
Why not sell a jig with instructions on how to build the desk, use a $90 router plus materials and create an instant crowdsourced mini standing desk factory? If I make one, I could easily make 5 more in probably half the time. And given the ease of manufacture, I have an almost zero risk chance to learn a new skill.
Sell the franchise (the jig plus instructions) and then others who just want the desk can pay the maker (at the source) an extra $20.
BTW, this design doesn't look stable enough. Needs either a tension wire or a wall support in the front and back.
Walk out with a new piece of furniture they made themselves but didn't require the huge upfront cost of tools etc.
