I see builds using 1) drag chains, 2) sleeving, and 3) sleeving using the tape measure trick. All three methods work. Personally, I used these drag chains. Recently a forum topic “advertised” a nice parametric drag chain for 3D printing.
Second question is a box for the controls.
Is there anything out there already made or could I pay someone to make one?
You don’t say what control board you are using, nor whether you have a display or not. I have a Rambo board with a display, and I 3D printed this box. Out on Thingiverse and Printables there are other boxes both for the Rambo and for other control boards. I’ve also seen builds using storage boxes for their electronics.
