I made one of these last night, but not without difficulty. Slic3r complained that there was a geometry problem that it "automatically corrected", and it filled in the main hole in the knob. I tried an STL generated by the Customizer, and I tried an STL generated by me on a local copy of OpenSCAD. Same error message, same gcode with no hole in the bottom of the knob. Running the STL through Netfabb cleaned it up, but I was surprised that there was a problem at all.

I picked all the default parameters (tapered, knurled knob, recessed top, no ring...) and only turned off the 3mm setscrew hole.

Has anyone else had issues with this knob script producing STLs that have errors?
great thing! note that adding a non-zero shaft fills the hole in the knob above the shaft (which has its own parameter) Still, great thing thanks!

Instructions

Open in Customizer or OpenSCAD. The OpenSCAD script contains some additional settings for advanced users.

Depending on the design of your knob and your printer, you may need to turn on support material and/or flip the knob upside-down before printing.

If you use the "recessed" cap type, your knob will have a divot at the top which you can paint with enamel paint if you wish. If you have several knobs on a device you could distinguish them by the color of this paint.

Depending on your printer, you may need to make holes 0.5mm or so larger than necessary (though you probably know your printer better than I do).
