2U Rack for RaspberryPi and Arduino

3d print model for a modular 2U rack for RaspberryPi 4, Arduino Mega and OLED display.

Features

The models are based on the excellent Thingiverse model, use OpenSCAD and have been extended to

• Increase depth to support Arduino Mega
• Increase height for Arduino Mega frame to support shields
• New tray to support OLED mounting

How To Use

• Install OpenSCAD, extend models and export STL's, or
• Reuse and print STL files without modification

Models

RaspberryPi 4 Tray

RaspberryPi 4 Frame

Arduino Mega Tray

Arduino Frame

OLED Tray for Freetronics FTOLED

Extension

The rack-config.scad defines core variables that configure all models:

/* Represents M5 radius bolt size */
bolt_size = 2.5;

/* Represents different lengths of devices - max should be chosen
arduino-mega = 101.6
raspberry-pi = 85
*/
device_length = 101.6;

/* If an arduino shield required, reduce number_to_fit to increase height, otherwise chose 12 or 13 if just raspberrypi.
    e.g. 9 for Arduino Mega
*/
arduino_shield = true;
