<p>Macro Keyboard powered by Arduino Pro Micro with printable relegendable keycaps.</p><p>Buttons are a remix, I adjusted them to better fit my MX switches.</p><p><strong>Requirements:</strong><br>- 4x M3 x 16mm Screws (M3 x 18mm also works)<br>- 12x MX Switches<br>- 1x Arduino Pro Micro (5V)<br>- 1x Micro-USB Cable</p><p><strong>Instructions:</strong><br>- Insert the 12 switches into the top<br>- Solder a cable through all buttons and solder it to one of the GND pins on the Pro Micro<br>- Solder each button to a digital pin of the Pro Micro<br>- Flash the program onto the Pro Micro<br>- Insert USB Cable into the bottom of the case and in the Pro Micro<br>- Put the case together, screw in the screws, they will hold without any nuts</p><p><strong>Print Settings:</strong><br>- Top Case: 0.2mm, no support, 15% infill<br>- Bottom Case: 0.2mm, no support, 15% infill<br><br>- Top Keycap: 0.15mm, 0.2mm first layer, no support, 15% infill (I used&nbsp;<br>Prusament PLA Vanilla White, it's nearly transparent with only 1 bottom layer)<br>- Bottom Keycap: 0.15mm, 0.2mm first layer, no support, 15% infill<br><br><strong>Labels:</strong><br>- Size: 15.75mm x 15.75mm or 16mm x 16mm with rounded corners</p><p><strong>Source Code:</strong></p><pre><code class="language-c">#include "Keyboard.h" #define buttonCount 12 const byte KEYPAD_0 = 234; const byte KEYPAD_1 = 225; const byte KEYPAD_2 = 226; const byte KEYPAD_3 = 227; const byte KEYPAD_4 = 228; const byte KEYPAD_5 = 229; const byte KEYPAD_6 = 230; const byte KEYPAD_7 = 231; const byte KEYPAD_8 = 232; const byte KEYPAD_9 = 233; const byte KEYPAD_ASTERIX = 221; const byte KEYPAD_ENTER = 224; const byte KEYPAD_MINUS = 222; const byte KEYPAD_PERIOD = 235; const byte KEYPAD_PLUS = 223; const byte KEYPAD_SLASH = 220; int keyPin[buttonCount] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 14, 15, 16}; //int keyCode[buttonCount] = {KEY_F14, KEY_F17, KEY_F20, KEY_F23, KEY_F13, KEY_F16, KEY_F19, KEY_F22, KEY_F24, KEY_F18, KEY_F15, KEY_F21}; int keyCode[buttonCount] = {KEYPAD_ASTERIX, KEYPAD_8, KEYPAD_5, KEYPAD_2, KEYPAD_SLASH, KEYPAD_7, KEYPAD_4, KEYPAD_1, KEYPAD_3, KEYPAD_9, KEYPAD_MINUS, KEYPAD_6}; bool keyState[buttonCount] = {false, false, false, false, false, false, false, false, false, false, false, false}; void setup() { pinMode(2, INPUT_PULLUP); pinMode(3, INPUT_PULLUP); pinMode(4, INPUT_PULLUP); pinMode(5, INPUT_PULLUP); pinMode(6, INPUT_PULLUP); pinMode(7, INPUT_PULLUP); pinMode(8, INPUT_PULLUP); pinMode(9, INPUT_PULLUP); pinMode(10, INPUT_PULLUP); pinMode(14, INPUT_PULLUP); pinMode(15, INPUT_PULLUP); pinMode(16, INPUT_PULLUP); Keyboard.begin(); Serial.begin(115200); } void toggleKey(int index) { if (digitalRead(keyPin[index]) == HIGH &amp;&amp; keyState[index]) { keyState[index] = false; Keyboard.release(keyCode[index]); Serial.print("Release Button Index - "); Serial.println(index); } else if (digitalRead(keyPin[index]) == LOW &amp;&amp; !keyState[index]) { keyState[index] = true; Keyboard.press(keyCode[index]); Serial.print("Press Button Index - "); Serial.println(index); } } void loop() { for (int i = 0; i &lt; buttonCount; i++) { toggleKey(i); } }</code></pre><p>With the default code you will map the numpad onto the keys. You can also use F13 - F24, but not all software/games supports these keys. (e.g. GTA 5 only F1 through F15, CSGO only F1 through F12)</p><p><strong>Counter-Strike Global Offensive Config:</strong></p><pre><code class="language-plaintext">bind "KP_SLASH" "buy m4a1; buy ak47;"; bind "KP_MULTIPLY" "buy vest; buy vesthelm; buy defuser;"; bind "KP_MINUS" "buy flashbang;"; bind "KP_HOME" "buy molotov; buy incgrenade;"; bind "KP_UPARROW" "buy smokegrenade;"; bind "KP_PGUP" "buy hegrenade;"; bind "KP_LEFTARROW" "buy p90;"; bind "KP_5" "buy sg556; buy aug;"; bind "KP_RIGHTARROW" "buy awp;"; bind "KP_END" "buy fiveseven; buy tec9;"; bind "KP_DOWNARROW" "buy elite;"; bind "KP_PGDN" "buy mp7;";</code></pre><p><strong>Credits:</strong><br>Original Keycaps - <a href="https://www.thingiverse.com/Mc_gee">Mc_gee</a> - <a href="https://www.thingiverse.com/thing:3791028">https://www.thingiverse.com/thing:3791028</a></p>
