This is a simple bracket I put together in Tinkercad to mount an LED light bar to my Ender 3 Pro. This will slip over the top rail of the Ender 3 (end probably others of similar design), sliding on from the end.
I made the bracket quite wide (40mm) to accommodate the supplied LED bar mount but the bracket can likely be used for quite a few other purposes.
Printer Brand:
Creality
Printer:
Ender 3 Pro
Rafts:
No
Supports:
No
Infill:
20
Filament:
Hatchbox PLA
Notes:
With 20% infill this thing will be quite strong - I don't see any need to increase that unless you're planning to use it with something very heavy. Since this prints on edge [by default] there are no supports needed (if your slicer thinks otherwise, its probably rotated the wrong way).
Post-Printing =============For anyone who might be interested, here's a link to the specific LED light that I used: https://www.amazon.com/gp/product/B076MS35CY/
Edit: I found another great use for this bracket - it's exactly the right width to clip a Wyze internet camera to! These are awesome cameras, easy to setup, and in this case can give you live remote monitoring of your printer all for about $20 USD. See the image below where I've simply used a large "paper clip" to attach the base to this bracket so it's facing straight down over the print bed. https://wyze.com/wyze-cam.html
