Ender 3 hot end mounted LED light strip mount. Will also fit Ender 3 pro
LED strip mount attaches onto the standard cooling fan & duct. There are 2 STL files included, one places the LED strip at a 5 degree angle, and the other at 12 degrees. I preferred the 12 degree version as it gets the light under the hot end better.
I installed LED light strips not only to the hot end, but also inserted LED strips into both vertical uprights, and mounted an LED light strip onto X gantry: see below for links to these.
I took power from the Ender-3 PSU, and converted the 24V DC to 12V DC for the LED strips king a buck as per https://howchoo.com/g/odk2ngrhztd/how-to-add-an-led-strip-to-your-3d-printer
I threaded the power wires inside the braided sleeve up to the hot end.
Fit the fan duct to the LED strip mount first, as per the photo attached, and then attach tis assembly to the fan. note if you take the fan completely off to fit this mount, there are 2x long screws and two short ones. The short ones mount at the top, and long ones mount the fan, duct and LED mount at the bottom.
I have designed a switch mount for the Ender 3 control to discretely mount a power switch for the LED lights.
