M5 Knurled Knob

Made this sized for an M5 nut to be used for bed leveling. Remix of http://www.thingiverse.com/thing:439239

You may need to size this up or down depending on your printers tolerances. resize X and Y only (not Z) as needed in increments of 2%.

You can heatsink or press fit this as needed.

I've included my openscad version of the original so you can tweak as desired. remember that you need the library from http://www.thingiverse.com/thing:9095
