Vỏ Raspberry Pi Pico (snap-fit 2 mảnh, không cần ốc)

A simple 2 parts snap-fit case for Raspberry Pi Pico. No screws needed. Back of case is open for wires. I use it to connect 2 ADXL345 and do the input shaper in Klipper 

Print settings:

• layer: 0.16 or lower
• perimeters: 3

To connect 2 ADXLs use the following pins. For the second ADXL you will need to use GPIO8, GPIO9, GPIO10 and GPIO11 according to the colors. Red and Black are the same. 

Klipper Configuration

[mcu pico_adxl345]
serial: /dev/serial/by-id/usb-Klipper_rp2040_use_your_id-xxxxx

[adxl345 head]
cs_pin: pico_adxl345:gpio1
spi_bus: spi0a
axes_map: -z, x, -y #update your axes mapping

[adxl345 bed]
cs_pin: pico_adxl345:gpio9
spi_bus: spi1a

[resonance_tester]
probe_points: 115, 115, 30 #update your position
accel_chip_x: adxl345 head
accel_chip_y: adxl345 bed

If you need a bed mount for ADXL take a look at this.
