I wanted a similar LED Light Bar for my Ender 3 as I made for my MK3s'. I used the openings from In3DSpace's design and moved the power switch to the other side. This is wired directly to the power supply. An updated model will be uploaded soon. You can purchase a completed kit from Desert3dprinting.com. Use an extrusion cover in the back to hide the power wires going to the power supply.
*Version 2 Coming Soon!
The author remixed this model.
