This a LED mount meant to illuminate the print head. There is also two strips pointed at a 45 degree angle towards the bed. I have integrated wire holders and three slots for zipties. There is also two pass through holes for hex key installation.
Both parts should be printed standing on end. A brim should be used. I printed the mount with thick walls and high infill for strength. I haven't had issues with flex or weak points. The diffuser should be printed in vase mode/spiralize outer contour. I used clear pla since I had an issue with white being to opaque.
