Knob Insert Source

Does anyone know of a source for metal inserts for knobs like the lighting panel knobs? I am 3d printing them solid and I started making a drill jig for getting the hole in the bottom centered. Next stop is figuring out where to get the metal inserts.

Is there somewhere that you guys have had good luck?

Also I keep seeing mention of Deadman's knob painting tutorial. Is there a link that I haven't seen to it? I have done a few searches and have not had luck finding the actual tutorial.

Thanks!

Not sure why you need the inserts they are on either Grainger or McMaster the paint tutoria is located in the right counsol knob in the for sale section. I will post a link when o get home.

here ya go a bit expensive.

Are you looking for the set screws or a sleeve to insert in your printed knob?

the metal insert for knob have threaded holes for set screws that seams to be what he wants.

Yeah that's what I was thinking everyone does? Can you use a set screw without a sleeve?

romeokilo has mentioned in his post he has purchased several of my knob from shape ways and been very happy with them . The knobs are made with a shaft and set screw holes printed in. He has not mentioned using anything but a tap and set screws. check out his build here on his thread.

I have sold a few knobs now to different guys and have not had any one let me know the material from shape ways has failed to hold a set screw perhaps RK can give you some advice.

Yes as long as the knob is threaded and fits well the set screw is to prevent the knob from falling off

The main thing the set screw is there for, is to keep the knob secured to the shaft so it does not spin .

I try for panel mounted dash aft encoders my self if available

I don't understand what you are saying

Hi, allow me to come with an alternative idea.

3D print them like this:

And let the printer do the hole in the middle, printing them solid takes way too long, and rarely keeps the shape of the knob.

This way you have an accual thread to screw the screw into when fatening to the shaft, and its also way cheaper.

Very creative idea, nice job

Thank you :)

It might not be all knobs are wide enough that they can use this, but most of them should.

Very hard to tell with out a reference next to the knobs or knowing the size of set screw. there is no way for me to tell.

Most knobs on the A-10 are less than an inch or 25.4 mm in diameter so there is not much meat to set a nut in

I use deadmans 3D printed knobs in my pit.

His knobs are printed for the real rotarys/pots, I just drill the holes out wider (6.5mm) to suit my cheap ebay rotarys and pots.

I use M3 set screws to hold them in place. No metal brackets or nuts, just drill and tap the plastic to M3 thread and the material holds the screws very well.

The Shapeways prints are very good quality, and with the frosted material they backlight very well.

I have only damaged one, and that was because I threaded the set screw hex head and couldn't remove it. Had to drill it out. Still use it but with an m4 set screw.
