Some really great things you guys have printed
After weeks of humming and hawing I've finally bit the bullet and ordered one.

I hope you have bought some filament.Some really great things you guys have printed

I'm a bit away from printing anything I fear. Its an (ahem) home assembly kit job coming from china (hopefully).
Should be entertaining.

Talking about forstner bits, I printed a jig for doing cabinet hinges.
Grabbed it off thingingiverse and worked perfect. Ill be ******** before I buy the jig from blum.

You might as well go to Lidl today and buy a plasma as well...

Of course not. I should be able to post the model files online somewhere if you like.

These:
Took a fair bit of time to remove those supports but they all came off eventually:
Getting this 5-pin switched potentiometer in and soldered to the wire was "fun":
I'll probably do a version 2 with better strain relief and the ability to drop the wire in straight, but it's good enough to test the principle.
All assembled: I'm not sure the screw is necessary really as the end caps are friction fit, but I thought it couldn't hurt. I need to shorten the screw slightly when I can be bothered.
It's amazing how obvious the extrusion lines are in that photo - they're much less obvious in real life.
In case you haven't worked it out yet, it goes here...
... and should give finger-tip control of the welding current. The switched potentiometer will start the arc when you turn the wheely thing towards you, then the current should get higher and higher the further towards you it rolls.
I'll test it tomorrow or Saturday and if it works I'll probably print version 2 with a better way of retaining the cable.

Very nice. I had been thinking a pcb smd resistor/trace network with a sprung button slider but thats as far as I got.
I did have a second idea, to minimise the size, to use an optical encoder/button combo from a mouse wheel and have an esp32 somewhere on the cable to set the resistance.. However the esp32 likely wouldnt survive the interference.
I've wondered how 6061.com has done his button product in such a compact package but Im not going to pay £250+ to find out!

I suspect I know
Pressure sensitive buttons are available - https://www.sparkfun.com/products/9375
I'm sure other cheaper sources are available, but that's the first I found.
