The main feature of this model is the ability to have a continuous pegboard the size you need. I made it so the board can sit on a table, making it easier to fix it on the wall with fewer screws. It's designed to use the modules from this link https://www.thingiverse.com/thing:537516.

The board has slots that fit a tinny bowtie joint to string them together. The joints are not meant to hold the boards in place; they are designed to align them correctly and provide additional support to keep them like one piece, but they must be glued to secure all the parts. I used hot glue, but maybe a stronger one would be better, like CA or epoxy. Hot glue is nice because it can be scraped later, so if I decide to expand the board, it'll be easy.

To make it prettier and with a better finish, there are borders to make the edges straight, and they are also glued in place. The majority of the weight of the board will be held by the feet, which can be screwed onto the tabletop to be sturdy. Doing this, it's possible to use fewer screws on the wall, since they are just enough so the board doesn't fall off. Using both the feet (pressed against the wall) and the stand-offs, the board will have a clearance of 1cm, which is the gap for the peg modules to be inserted.

There are three board sizes so you can build it according to your space: large (203mm x 203mm), mid (203mm x 126.9mm), and small (203mm x 76.1mm), and borders for each size, with 3.175mm width. The holes are 7.1mm in diameter, 1 inch apart from each other. I used one foot per board, but you can use as many as you want. To glue the board pieces, lay them down on a flat surface and insert the joints and borders. Once the layout is right, spread your glue where the edges meet each other. The idea is to have glue only on the back, creating a clean front.
