Heres a parametric pegboard base I made for F360. You simply open the file in fusion, then go to change parameters, and make the base as big as you want, adjust the hook size, angle etc. If you'd like to make a bin or just a blank block to cut your part into you can just extrude the face then shell or combine bodies.

Due to the way I did the math the number of pegs has to fit evenly between the width of the pegboard. so if you have a 5 wide base you have to either use 5 pegs, 3 pegs, or 2 pegs (one on either end) Ive also Included a pegboard example to test your designs to make sure they'll fit. The pegboard follows the same parameters as the base. I've only been using cad software for a few months, so I'm sure this isn't perfect but it allows me to make things for my pegboard much faster.

In practice the hooks aren't really strong enough to support large objects like power tools, but they work good for smaller things like drill bit holders, hardware bins etc.
