This is a Fluorescent light bar mount for ceiling mount or for standoff mounting to ceiling. I could not find a suitable mount anywhere just to print, so I designed my own. I recommend PETG as it works better in higher temperatures and I am sure ABS will print this just fine.
The dimensions are length 120mm, width 156mm, height 44mm
Mounting holes for fixture included, the holes on each side may need to be elongated to fit different styles, but easily fixed.
