I still tag is as a remix just because it's not 100% my original idea, but I redesign it from scratch on Fusion. And I also includes the STEP files so other can easily remix it. QMK Firmware source for Pro Micro is also available on my QMK fork. The default functions are quite obvious from the keymaps, except for the left most key, it's a custom shortcut to mute/unmute Zoom meetings (been having a lot of it recently).

As pictured, mine features:

• Thinner front plate so the switches will just click in, instead of snug fit.
• Screw holes for under desk mounting.
• Mounting place for Pro Micro, a bit snug, but you actually want it snug here.
• Better tolerances for EC11 rotary encoder.
• The knurled knob is also 3D Printed.
