Mount post for a print bed light. The light in question consists of an ordinary USB extension cable and one of these nifty USB LEDs with a touch on/off/dim switch.
The mount uses the two screws holding the Ender 3v2 mainboard housing in place and is angled at 45° to illuminate the print bed.

Supports ARE NEEDED ... tons ... I recommend using Cura's tree supports, touching build plate only (unless you slice in a different program that does not offer that choice). Print in whatever orientation you like, I tried the orientation the .stl comes in.
