For M3 stainless steel nut that are 5.5mm wide.
I tried the other thumb wheel on here, but it did not fit the M3 nuts I got from my local Ace Hardware.
I used a black Sharpie marker to give some contrast.
November 2016 UPDATE: I have a new design that is smaller, a bit pointier, and works with more printers. Check it out here: small thumbwheels
How I Designed This
At the time I made this, Onshape did not support text so I made my own characters.
If you have an Onshape account, I made the file public: https://cad.onshape.com/documents/f3fdcd0c31b648a4bc42e302/w/54c2055210294548a7624886/e/8df74fd910da407f98be51b6
(bad link fixed)
I also added variables to the Onshape file.
Nut size:
-- #nut_width is set to 5.5 mm
The offset tolerance--make larger if nut is the correct size but too tight:
-- #offset is set to 0.2mm
Instructions
Best printed at 0.1mm layer height. I used 25% honeycomb fill using S3D. May want to print at 0.2 mm for a quicker print and then use them to fine tune for a better print.
