My version of a Unitak3D lightbar holder for the Ender 3v2, and possibly others.

I combined some of Phoenixblade70's lightbar holder (https://www.thingiverse.com/thing:5936592) with some of Kim3043's beagle bracket (https://www.thingiverse.com/thing:5370716) as I preferred the way the beaglecam bracket attached to the frame, and added a few of my own small modifications.

You'll also need the switch holder from https://www.thingiverse.com/thing:5384261

I used four M3x12mm screws that I had from another project to attach the bar to the arms, and the light switch to one of the arms. The holes were a little tight, so you might need to drill them out.
