A set of risers for a tabletop or desktop setup. The base risers will raise a board up, and the middle risers can be placed to rise boards up off of boards.

I made this during Work from home, so that I could turn my table into a standing desk situation. The SCAD file is fully customizable for any board size, riser height, and all the other relevant variables. I hope this helps you out as much as it did me.
