Knob thumb Screw M2-M3-M4-M5-M6 socket

I liked the original design made by edmar, but required the hex section to protrude from the suface. Storing the knobs together with the bolts, removes the need to track down suitable bits / allen keys when you need it. Depending on yor use case, you may still need to find one to properly tighten the bolts.

After a quick adjustment in Fusion 360, made a scaled set for M2, M3, M4, M5 and M6 bolts.
The M2 version is tiny, and may end up as useless. The one I printed do work.

Changed the hex section to protrude from the bottom, making the knob sit flush atop of the bolt.
