Nut knobs are useful for many purposes in DIY projects.
All the different knobs in the gallery are made with this 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.
