The miniaturized spectrometer is composed of 4 fundamental pieces, and a clip to attach it to the smartphone. 

It is recommended to print the spectrometer in black color, to avoid light to penetrate. 

 

The components of the mini-spectrometer to be printed in 3D are: 

• Base (download the STL file upb_base_01_2017.stl)
• Slider (download the STL file upb_slider_01_2017.stl)
• Cap (download the STL file upb_cap_01_2017.stl)
• Tube (download the STL file upb_tube_01_2017.stl)

Base

Slider

Cap

Tube

The 3D printing was validated with ABS filament in a 3D printer (Flashforge Creator Pro) with 0.1mm of precision, with Makerbot printer software.
