I am getting to a point where I should be thinking a bit more about electronics and at the moment in particular about cable management. I am wondering if I would need a cable chain and if I need what to do about that. Obviously considering the rather tight budget buying a commercial cable chain seems not too sensible thing to do, not to mention the ones I eyeballed seemed a bit too big for my purposes.

So I am primarily considering a possibility of cutting one out from 2mm acrylic during the same cutting trip I would be doing for the rest of the laser cut acrylic parts. Edit: The relevant files uploaded to GrabCAD for this cable chain: https://grabcad.com/library/laser-cut-cable-chain-1 - note that at this point this is just an idea and has not been tested in reality.

The cable channel would be 16 x 7 mm and 180 deg turn would be approx 45 mm turn radius. For now this is just an idea. Perhaps I can get away without one, but getting one afterwards if I do need it after-all might be hassle. Alternatively I have seen some clever usage of zip ties, for example, for adding stiffness and guidance to a cabling.

Bonus content. A front, side and top renderings of the planned machine. I have let it sit for few days on my hard disk and taken another look at things if they all still make sense. Added couple of holes here and there, rounded couple of corner where it made sense. Overall I am getting reasonably happy with it so will start figuring out how much acrylic sheets I would be exactly needing for getting it cut out.
