Wall/roof mounted spool holder for 3kg spools

I needed a spool holder for a big filament spool I bought, as it did not fit on my Ender 3. The spool in the pictures is 2,5 kg, but 3 kg spools will also fit. It's very sturdy and can easily hold the big spools.

The screw holes are 5 mm, and countersunk.
