Ultimate Nut Knob Generator

Nut knobs are useful for many purposes in DIY projects. All the different knobs in the gallery are made with [this](http://www.thingiverse.com/apps/customizer/run?thing_id=713300) Customizer. I have added some sample knobs for M3 nuts as there are most common used size for 3d printer. The screwdriver handle for standard 1/4" hex bits is surely a unusual application, but it works great. Especially if you need a extra small one for your project. If you got problems getting the knob in place, simply heat up the nuts a bit (about 60-80 °C / 140-175 °F) and it easily slips in place. Please refer the instructions to see the setting I have used for the sample files.
