Spectroscope to bin near-UV LEDs from AliExpress

I bought a few 1,3 and 5 Watts 400-410nm LEDs from AliExpress shops and I wanted to confirm and/or select the correct 405nm wavelengths out of these for a 70-100 Watts panel.

For this purpose I designed a small FDM-printable spectroscope.
Details and models can be found here:

Maybe this is something of use for others here as well.
