Has anyone made their own version of the Kreg ACS or Festool MFT? I have an idea for creating one but want to see how y'all did it.

I’m planning out my workbench and trying to think ahead to incorporate a dust collection system. Mostly amateur woodworking and small projects/hobby builds, nothing too heavy or commercial. Two questions for those who have built their own systems:

1. Is there a standard or minimum pipe size to use? Was thinking of putting all of the pipes in/behind the bench in order to hook up a system in the future.

2. Since I have an L-shaped bench and will be around 36” wide, I’ll end up with a lot of difficult to reach space in the corner underneath. Has anyone ever built a system that could fit under a bench in that kind of corner dead space?

In my opinion the best way to store tools in a small workspace where the floorspace is limited is via a tool wall for the tools that aren't super specialized and you need them to be at hands reach. If you have all the tools in a toolbox you are most probably not gona make anything because you won't want to deal with looking through the box, also the tools might get damaged.

Furthermore although french cleat systems are nice for big woodshops because they enable easy placement adjustment of everything, for small woodshops covering a wall with plywood is the best solution spacewise because you can have the tools much more closely packed. Bonus point less screws are needed to go into the wall.
