This wall mount is specially designed for the Minecraft torch-LED tealight holder , which you can find here. [https://makerworld.com/models/927423](https://makerworld.com/models/927423) 

On the back there is an invisible hole for the screw. I used  IKEA TRIXIG  505.611.83 round screw head 4x16 mm. You can use al longer screw depending on the wall.
We used the PLA Bambu filament

Thank you @wontonnn for the great torch design.
