About this 3D model

One of the small frustrations in my life is the lack of captive nuts on the bottom of a printer bed. Leveling the bed is a crazy-making two-handed test of manual dexterity: a wrench in one hand and a screwdriver in the other, and various bits of inconveniently positioned bed hardware. I thunk to myself: "What if I had a tiny wrench head I could glue in place?" The OpenSCAD routine takes a parameter for the nut size, in mm, across the flats. If you still live in Imperial Land, you can avoid all that nasty conversion math here: http://mdmetric.com/tech/cvtcht.htm In the Customizer, you won't see an apparent size change as you scale it larger or smaller. Trust that the STL generated will be an appropriately-sized Nut Leia. If you don't have your digital calipers handy, you can get a measurement across the flats of your favorite SAE nut here: http://www.engineershandbook.com/Tables/nuts.htm Metric here: http://www.slideshare.net/tejasudas/dimensions-of-metric-hex-nuts ___ **ATTENTION** This work is licensed under the [Creative Commons - Attribution - Non-Commercial license](http://creativecommons.org/licenses/by-nc/3.0/).
