A knob for a doors, cabinet or what you like
The knob has a hole 5.5mm.
You can use a bolt or screw, i have used a 4x60 screw to stick it with and it work fine
There is a little lid to hide your bolt or screw, i have used a little drop of glue to make sure it stay in, but sametime always could pull it out if i dont wanna look at it any more.
I printed with no support and with Pla and petg would work just as fine.
Good luck and happy printing.
