Ummm... The screw HOLE must be cylindrical to allow the screw head to spin while the screw is being inserted?

Hi Leonard, It actually was a hex  in the beginning and somehow got changed and never came back to hex.   I need it to be hex because it is capturing the head to prevent turning.

  # rotate([180,0,0]) screw_hole("1/4-20",length=H,head="hex");

What I do, then, is create a screw and subtract that from the base object: diff() { cuboid([W,L1,H],anchor=[-1,1,-1]) rotate([180,0,0]) scale( [1.01, 1.01, 1 ] ) #screw("1/4-20",length=H,head="hex"); } On Thu, Jan 12, 2023 at 2:02 PM Bob Roos <roosbob@wybatap.com> wrote: > Hi Leonard, > > > It actually was a hex in the beginning and somehow got changed and never > came back to hex. > > > > I need it to be hex because it is capturing the head to prevent turning. > > > Thursday, January 12, 2023, 11:01:09 AM, you wrote: > > Ummm...

  # rotate([180,0,0]) screw_hole("1/4-20",length=H,head="hex");

The screw_hole() module creates a counterbored hole so that you can inset the screw. Using screw() instead of screw_hole() would be one workaround, though you might need to manually oversize the hole. I'm not sure if there's a better solution. Adding an option to screw_hole() to do what you want might be a possibility, but the hex head is the only head type for which is would change anything, so I'm not sure that makes sense.

Hi Adrian, Yes, that is exactly what I wanted but I can't seem to get the hold to appear in the F6 render.

The semicolon after the mount module means the screw is not a child so the diff does not apply to it. Remove the semicolon. Add braces if that makes things more clear.
