This pegboard panel were meant for those who wanted to have their own pegboard wall panel which should be way more expensive compared to just buying/ordering the pegboard from local store or online. The problem to that is often they can be quite heavy and too big to work with, not to mention that requires some tinkering to it if you decide to fit them in a very limited space.

These are 3d printable panels that you can slowly build yourself to make it bigger and larger by using picattiny rail to couple them together.

Use any M3 with at least 8mm length so that it will able to lock itself to the rail, 30mm to go all the way across. use 2 M3 on each side if you're planning to use 8-14mm M3 bolts
