Tools/Materials Needed:

• 3D Printer and filament
• Arduino nano
• RFID Reader
• RFID Tags
• Rotary Encoder
• Material Samples

Instructions:

1. 3D print the enclosure at 100% infill, and the sample holders at 50% infill.
2. Wire together the Arduino, RFID reader and rotary encoder, then snap into the enclosure
3. Slide the material samples into the sample holders with an RFID tag in between
4. Upload the Arduino sketch to the Arduino
5. Download the Human UI and Firefly plugins for grasshopper
6. Run the grasshopper script, and make sure the arduino is connected to it by serial port
7. Add the data for the correct material to the .csv spreadsheet and link the proper textures
