CV19 Lockdown Project???

Paul’s 3D printed LowSpec instrument is giving very good performance and is very cost effective.

Well supported on the https://groups.io/g/astronomicalspectroscopy

Many of us use BASS Project for Spectral processing. It has a comprehensive manual and well supported.

Remember if you build/buy a spectrograph it can also be used with a suitable scope as a spectroheliograph (SHG). Then you can safely image the solar disk at any wavelength CaK, Mg, Fe, Na, any of the hydrogen Balmer lines etc. etc.
Fulvio's good eBook on his SHGs is worth reading.
English version here:

Rob,
I believe for the immediate future the amateur options for spectrographs will be dictated by the growing interest and capabilities of the 3D instruments.
There are many design options still to be successfully “transferred” to 3D printing. Interesting times.
