Hello I am looking for a design for an electronic box, the requirements are:
-EXTERNAL
-Must fit a buck converter, pi 3B, mainboard and psu
-It does not require a screen mount
I am not asking for you to make one, I just search for one, I couldnt fidn anything exacly like this during my research
TeachingTech on YouTube has a customizable box that may work. Here is the Thingiverse link: https://www.thingiverse.com/thing:3688967
He also has a ton of instructional videos about designing your own parts, so check them out as well.
However, if you have specific requirements for future projects, you are going to be better served by learning CAD. I promise that once you learn how to design your own parts, the usefulness of your printer will skyrocket.
I started learning Fusion 360 in 2020 and it has absolutely been worth it. I will say that if you are moving from TinkerCad to proper parametric modeling, the learning curve will be extremely steep.
