Hello, I made a tube attachment for a billy shelf to hang my kitchen items on. the diameter of the pipe I use is 2 cm and the screws used are 2.5x15mm. Of course, the qualification can also be used for many other things, there are no limits :)

i printed the bracket on an ender 3 v2 with a layer height of 0.25mm and 4 outer lines and an infill of 35%

I would be happy if you would post your prints and your ideas here.

have fun printing :)
