This is a very simple mount for common aliexpress light bars.

Most of them use 4mm cubed holes for usually vertical mounting, but I used it to mount it to a 2020 extrusion on my printer. Fits most common printers such as vorons and ender 3s (also various clones of it).

You will Need:

• Lightbars (duh)
• 4x M5 T-Nut
• 4x M5x8mm (If countersunk, use M5x10mm)
• A Printer

I used these lightbars:

but these also fit (tested):

Personally I reccomend the aliexpress ones (cheaper, easier to solder in a ARGB socket)
