Prusa i3 MK3 printbed bed lights

I always wanted to install a fixed light for monitoring the first few layers without using a flashlight. This build consists of three pieces, two of which can be printed in PLA, or even better, some kind of PET due to the possible heat from the print bed at longer prints. The rail mount has to be printed in a more flexible material, like TPU. It needs to be bent to snugly fit into the rails. Tightening happens when you screw an M3x8mm screw inside, which presses the TPU outside and prevents movement. Position it so that the extruder doesn't hit it at max deflection. The mount is designed for these types of LEDs: https://www.amazon.com/gp/product/B00JP32S9O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 You need to print the angle.stl file two times - one mirrored because of the inner conduit for cables. Place the mounts so that the cables come out at the back of the mount, which can then be routed under the rails for a clean-looking print bed light. Please leave a like or comment if you have any questions. Enjoy and happy printing!
