About this model

I made this LED bar holder for my Prusa i3 MK3. It's the same concept as agniusm's but I made this version so the LED bar snaps on the brackets and then the brackets snap onto the hex holes located in top of the z-axis rod supports holding it more securely. i noticed less glare on the bed when the LED bar is held at an angle so this version mounts the bar at a 20 degree angle. This was designed for the MK3 so I don't know if it will work on the MK2 unless someone confirms it. I printed the brackets out of ABS. Since the brackets are designed to snap in place PLA may or may not work, I would think petg might be a good alternative. I purchased the light here for less than $4.
