BOYI GMK67 Keyboard Volume Knob
 

Keyboard Volume Knob to add some customization to your GMK67 from Amazon/AliExpress.

I printed at 0.12 layer height and recommend no brim touching the Knob STEM. If it is, you are likely to break off the steam when removing the supports.

Print with no brim or if you do 0.3-0.4mm away from the part and allow the tree supports to hold the knob after it reaches the higher portion.

You can modify this as you wish to make it lower or different patterns. It is also a tight fit so be careful to not break the stem when installing. However, it will never fall of.
