Encoder & Knob dimensions clarification

[hoijui]

I would like to clarify some things for me, and would offer to then adjust the build-guide accordingly, if you wish so.

You suggest a short EC11 encoder. The one you give as an example has a shaft-height of 15mm.
20mm and 15mm seem to be the most common heights, but there are also 12.5mm and 9.5mm. I imagine those would be pore problematic, to find a good know for, and I don;t know if it makes sense to choose them that short anyway.. could it make sense, or would it maybe be good to recommend 15mm height directly?
The knob you designed, if I saw that right, has a height of 15mm and a diameter of 22mm. Does that mean, the encoders shaft-height and the knob height should be equal?
I would also add that the 22mm you suggest are the diameter.
Is 22mm also the maximum diameter to not block the keys or fingers while one is not using the knob?

Hi there. Sorry for the late reply I didn't catch on your post. So the max diameter of the knob is determined by the hole in the provided case design. I measure it to be at around 23mm but I would stick to 22 for safety. For the stem length it depends very much of the knob design you choose. The 3d design knob is not my design so I cannot realy help on this, also because I have used aluminum knobs bought on Aliexpress. What I can say is that you would more likely end up with a too long shaft than a too short one, depending of the knob you pick. With a shaft too long, you would end up with the knob extendind too much which is not good looking but without any impact on functionalities. I would not go above 15mm, 12.5 will work in most cases. The set screw being at the bottom of most knobs, 9.5mm should also work without issues. There is no real definitive answer, it depends of your choice of knob. But I suggest sourcing a nice metal knob, this will improve your overall experience. Also I would recommand a more conical shape knob to minimize interactions while typing. Purely round knobs may be annoying as they may interfere with you fingers when typing fast. Hope this will help.
