Work From Home Multi-tool

When I made this design, I decided to make a mobile multi-tool for working at home. My design has a pencil holder on a flat surface, where you can put sticky notes or whatever you want on it, a slanted surface to put a notebook/paper, so you do not have to strain your neck as much to look at it, a lip on the bottom so the paper/notebook doesn't slide out, and a backboard with holes all over it so you can hang notes on it, all in a 22" x 12" x 18" design. It is made of plastic so you can carry it around and work on things wherever you are. When I tried to make the pencil holder, I couldn't get a good design with two octagons, so I made three octagons and lined them up with a 3D sketch, and if I could redesign this again, I would either change the dimensions or split it up into multiple parts as it is not too portable. 3D printing my design can make my design cheaper and more durable.
