While building my AM8, I decided to route my power through the back. I picked up some 1/2" tubing from Harbor Freight to wrap the cables in, and I needed a nice looking way to attached the cable to the frame.
These clips will snap tightly into a 2040 extrusion. Once attached, you can easily removed them. You could use them for anything you like, not just routing cables!
If you find a creative use for them, please share!
There are three models available. They are all the same, just different heights. In the picture of my printer, I'm using the 20mm clips.
Adjust the infil accordingly. I found 40% made them nice and strong so they didn't break while attaching to the frame, but not too strong that I couldn't flex them to attach or remove them.
