Summary

Design your own custom knobs!

Many different kinds are possible.

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).

So this is AWESOME... but... I'm having difficulty keeping the Hole Depth when I create a Shaft Length. I create for example a Hole Depth of 15mm and voila! it makes the hole inside the knob. but then when I create a Shaft Length of oh say 8mm... the Shaft Length appears at the bottom of the knob but the Hole Depth inside the knob becomes flush with the bottom of the knob, or VERY shallow.

Help!?

Wow! One of the knobs on my stove just broke, this should be a useful replacement! Thanks!

Life would really stink without a 3D printer, to buy a replacement would be 50$ :/

Great work! Lost the knob for the choke on my snowblower, and had a look here. This is just the ticket!. Thanks a bunch!

Absolutely brilliant piece of work, Charlie! Thanks for the effort of putting this into Customizer, you've inspired me to look into how to do that. You should put a pointer to this on instructables.com -- the community there can be a lot more appreciative than they seem to be here on thingiverse.

i get this making one with a brim:

<JSON::ParserError: A JSON text must at least contain two octets!>

Perfect!
Had just to increase your 0.001 or .001 a bit (replaced by a variable) to open the hole for the shaft.

There are far too few comments here for such a great piece of work. This is insanely useful, thanks for making this customizable. Awesome.

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!
