LED Light Diffuser for 1515 Ally Extrusion

thingiverse

This is a simple clip that holds "5mm" LED strip in the grooves of 1515 extrusion and diffuses the light. It can be cut to length with snips and is also useful for holding wires in the grooves, keeping your project tidy and nice. I used it in each of the vertical bars in my kossel 3d printer so I can see what's going on. I just wired it up to the power supply via a switch which I made a handy clip to retain it between the bottom two bars (https://www.thingiverse.com/thing:3966354). It does flicker a bit when it's printing so it's nice have the option to turn it off so I don't get a huge headache. It takes a bit of force to ram it in the groove: I found if you start at one end and use a rounded tool (I used the back of my tweezers) to push it in along the length it's not too bad. Once it's in it can be slide up and down fairly easily. If this is too long for your printer let me know and I'll knock up a short one, although it was pretty easy to make using onshape. As usual once I got something that was good enough I stopped designing but you could probably improve it if you feel like it.
