I liked the idea of a honeycomb pattern to freely organize screwdrivers and other things from toya (https://www.thingiverse.com/thing:3018389)
But the solution had some flaws which forced me to redesign it.
I do use Pegboards from Perfonet (http://www.pegboard.perfonet.de/de/das-pegboard/)
This can be printed without any support. I tested it with 0.25 and 0.20 on my Prusa Mini and it works.
If you want to have the hooks with a clean bottom finish, support needs to be added for hooks.
Otherwise, it is recommended to extend the perimeter. 4 outer shells are especially important to keep the hooks in place and strong enough :)
Based on a user comment, this works with Mastercraft Pegboards too.
The author remixed this model.
