Hand tools and fabrication machines
The first thing you need to do is to start making lines to create the grid, like so:
After doing that, you need to start drilling 1 hole on each corner.
In my case I drilled more than 1,00 holes. It took me a couple of hours to do it, half way through I thought to myself, I should pay next time. But when I finish I was so proud of my work and understood that being a maker is precisely that. Building something yourself that perhaps you can buy already made, but the fact that can build it excites you.
At the end I got what I needed, what do you guys think?
