Macropad with Keycaps (AutoHotKeys script)

For soldering instruction check out: https://www.printables.com/model/269757-stream-deck-marco-keyboard

Make a test print of the base to ensure that your pro micro fit is snug. I did not have a need to glue mine.

AutoHotKey Script

Read through the script and replace the paths. Copy the scipt into your startup folder. Run the script as administrator if you wish for programs to be launched as admin (mainly powershell)

; This is a script for AutoHotkey to be used with a Macro Keyboard assigned with keys F13-F24

Recommended settings for keycaps

Layer height: 0.07 mm

Infill 20%

Enable ironing for all top surfaces

Support enabled (can print without if you printer is dialed in well)

Speed 50%

Heatbed 65° (default 60°)

Flow Factor 90-95

Scale to 98% if the keycap feels loose

Remember to add the color change in your slicer program
