Pack Knob prep:
The Knob is 3D printed and has “support structures” to enable the internal structures to be placed
at the correct locations. I first use pliers and then a small straight screwdriver to pull and scrape
the support structures out of the inside of the knob. This can leave a lumpy surface, but it is not
visible once the knob is mounted.
On the left is the part as you will receive it and the part on the right has the support structures
removed:
