From what I can tell the threads on a Dremel rotary tool are 19 mm x 2mm (at least the one I have). Nudge nudge wink wink say no more.

I love the fact that this exists BTW. Kudos to creator Walnetto.

I bought a cheap blank and kiosks and hardware stores are saying they can't make it. (cheaply at least) I turned to my 3D printer for answers in combination with what creativity I can muster. I'll get it done one way or another on my own. Something like this would be my first choice tho.

I'd be curious to know what speed you printed this as well as if you printed the parts in the same orientation as show and if so did you generate supports?

At .2mm layer height, 100% fill at 45mm/s this is an ~8hour print. Change the layer height to .1 and 15-16 hour print.

I printed at 0.1mm layer height 100% fill at 60 mm/s I used Cura as the Slicer
I used Cura's preset for Normal Quality
I printed the two part separately
No supports
I oriented the parts largest flat face on print bed see the screenshot example

Cool how well does it work ?

I have successfully made a working key, there is a lot of chatter in the cuts the tolerances are not as perfect as a design using liner bearings and a shaft would be. Using a new blade helps, keeping the guide steady against the key and working slow and spraying it with water keeps from melting the holder. Using ABS instead of PLA would probably be a better idea. I am thinking of working on a better key clamping system, the screws can be stripped too easily.

Nonetheless ! its a great start. not that it cost a lot to get a key made but still! why pay someone when we can make it ourselves! I still think its a good idea that shows home 3D printer Rocks!
