EDIT - I no longer use Octoprint(PrusaConnect works great). There is a script below to just run on an Raspberry Pi.

This is a two button panel I designed for the front of my IKEA LACK enclosure to control a relay for a power strip via my Raspberry Pi running Octoprint.

Included step file for remixing button faces if desired.

Fits in 40mm x 19mm hole. Friction fit.

Uses (2) Micro Tactile Push buttons - 6x6x4.3 buttons in an assortment or separately.

This button panel triggers system commands via the Octoprint plugin Physical Button to turn the relay trigger pin on and off. I have a relay box controlling power to a power strip for fans/lights which was already setup with the Octoprint plugin PSU Control.

On: raspi-gpio set 22 dh
Off: raspi-gpio set 22 dl

To route wires in to the enclosure, I had to drill a hole up from the inside to route my wires to. Cover the front in painters tape and paper so you protect the finish while using a jigsaw to cut the hole marked with tape.

Code:
#!/usr/bin/python3
import RPi.GPIO as GPIO
import time
GPIO.cleanup()  # Clean up any previous GPIO settings
Pin configuration
INPUT_PIN_1 = 37  # Physical pin 37 - I on button input
INPUT_PIN_2 = 35  # Physical pin 35 - O off button input
OUTPUT_PIN_1 = 7  # Physical pin 7 - Power Strip Relay control output
OUTPUT_PIN_2 = 33  # Physical pin 33 - LACK servo duct control output
GPIO setup
GPIO.setmode(GPIO.BOARD)  # Use physical pin numbering
GPIO.setup(INPUT_PIN_1, GPIO.IN, pull_up_down=GPIO.PUD_UP)  # Input with pull-up resistor
GPIO.setup(INPUT_PIN_2, GPIO.IN, pull_up_down=GPIO.PUD_UP)  # Input with pull-up resistor
GPIO.setup(OUTPUT_PIN_1, GPIO.OUT)  # Output pin
GPIO.setup(OUTPUT_PIN_2, GPIO.OUT)  # Output pin
Variable to store the state of OUTPUT_PIN_1
output_pin_state = GPIO.LOW
GPIO.output(OUTPUT_PIN_1, output_pin_state)  # Initialize OUTPUT_PIN_1 to LOW
GPIO.output(OUTPUT_PIN_2, output_pin_state)  # Initialize OUTPUT_PIN_2 to LOW
try:
    print("Press Button 1 to set OUTPUT_PIN_1 HIGH, Button 2 to set it LOW.")
    while True:
        # Check if Button 1 is pressed
        if GPIO.input(INPUT_PIN_1) == GPIO.LOW:  # Button pressed (pulled to ground)
            output_pin_state = GPIO.HIGH
            GPIO.output(OUTPUT_PIN_1, output_pin_state)
            GPIO.output(OUTPUT_PIN_2, output_pin_state)
            print("Button 1 pressed: OUTPUT_PIN_1 set to HIGH")
    # Check if Button 2 is pressed
    if GPIO.input(INPUT_PIN_2) == GPIO.LOW:  # Button pressed (pulled to ground)
        output_pin_state = GPIO.LOW
        GPIO.output(OUTPUT_PIN_1, output_pin_state)
        GPIO.output(OUTPUT_PIN_2, output_pin_state)
        print("Button 2 pressed: OUTPUT_PIN_1 set to LOW")

    time.sleep(0.1)  # Small delay to reduce CPU usage

except KeyboardInterrupt:
    print("Exiting program...")
finally:
    GPIO.cleanup()  # Reset GPIO settings
