I built my spectrometer with spare Lego parts I had, but now I need to know what size cuvettes are used so I can source the right ones.

Hi @joquendo, we use 4.5mL Square Spectrophotometer Cuvettes, but if you're working with your own legos you can adjust to accommodate other sizes as well. Let us know how it goes!

That is a fair point. Not sure why I didn't think of that. Thanks. I also made a few mods to my build. I extended the main housing to add a small compartment for the ribbon cable as well as a few flat pieces to cover said compartment allowing the space of 1 flat brick for the cable leading to the Raspberry Pi. I also added a 2x4 flat tile to the bottom of the Raspberry Pi with a hot glue gun, to that it can mount to the housing. WP_20190511_00_39_54_Pro.jpg

Awesome! They're just standard 1cm x 1cm ones. They don't fit amazingly in LEGO so I'd love to figure out a 3d-printable holder!
