Hi I am willing to design my wasteboard with a M5 hole/insert grid (spaced every ~5cm which sounds a good value looking here and there). I plan to use my lead cnc to make it (would be more precise than doing it by hand with a drill). I have designed the board in Fusion taking care of the 3 rails under. But now I realize that it is also full of L Bracket: the one that maintain the board can be moved (I need to take care of it anyway) but not the one maintaining the rails. So as everyone need a wasteboard, I wonder if there is some design files somewhere to (re)start with?
