Knobs for metric bolts and nuts M4 - M5 - M6 - M8

For various projects I need to transform bolts or nuts into knobs.

Here are some models for the metric size M4, M5, M6 and M8.

On my printing device I like to have a brim, including and upmost when there is a hole facing the plate. This is why I sometimes include a 0.2 mm brim in my model and don't rely on the slicer to generate the brim.
So you will find here some all-in one models in order to print series of knobs.

However if you prefer to rely on the slicer to mange the layout, the quantity and the adhesion, I have included the individual parts.

In order to create a knob for a bolt you will need a part 'A' and a part 'B'. Il you create a knob out of a nut you will need a part 'A' and a part 'C'.

Obviously because of the small size the M4 model is quite tricky to print and adjust, but with the good settings it is manageable.
