This light bar holder was designed for the UCL035S-UL on the AnkerMake M5C. The light bar is available at Home Depot. You will need to print 2 of these to hold the light bar. After sliding the light bar into the 2 holders, place it along the top bar where it will click into place. While this was originally designed to face the front of the printer, you run the risk of breaking the holder by colliding with the hot end on taller prints. Because of this, it is recommended that it be placed facing the back of the printer. An optional light shield accessory is also included in the files. To print the light shield on the Ankermake M5C, you will have to rotate it 45 degrees so that it lays diagonally on the printing surface. There are also cable routing accessories for the light bar on my profile. Link to cable routing accessories: https://makeitreal.ankermake.com/models/7a1166bdcb2711efa39f7248bb1359c9/
