Two questions, why aren't each of the sides made made from a sigle piece of plywood? Also, it seems to me, watching the video commercial for the Variér Furniture that leaving the center of the bottom part empty would allow the feet to touch the ground comfortably.

Thanks for your comment!

> why aren't each of the sides made made from a sigle piece of plywood?
That is due to the size of my machine(Rockler CNC Shark Pro).

Yes, I originally wanted to leave the part empty, but I didn't do that for its strength.
I want to revise it.

no tracing needed. Just apply printer tape to the wood and glue the plan on. You can work on it and pull the plan off pretty simple.

What are those circles in each corner? You used a CNC-robot - isn't that one able to cut that without such marks like a wood worker would be able to?

Miilling machines usually use an endmill to cut materials
so when you cut a rectangle, it will be rounded because of the roundness of an endmill and you cant get a correct rectangle.

So you need to make a circle in each corner.

Ah, ok, didn't know that. Well, could also be a design thingy. Anyway - well done.
