Using my 3D Printer. I made a Spectrograph.

With my 3D printers. I was able to make the main body of the spectrograph that allowed me to install the slit, grate, and optics needed to have a fully functional Spectrograh for a little under $800 US. I have 2 versions of the grates. One for low-res (300 nm) and one for hi-res (2400 nm). The 300 grate is for my filter testing and the 2400 would be good for solar work. Overall, it was a fun project proving that I Won the filter lottery... ;-)
Here is the link that got me going with the project:

This might be my next project. Really like the way you show that it is possible to make something of good quality without breaking the bank.

Thanks Dave I can't stress enough that using PLA might get you in trouble. If you make the Sol 'Ex version of this for solar work. You will need a sun shade to keep the direct sun off the unit. As I mentioned, PET-G is a higher temp fliament and will stand up better to solar heating. I have 2 printers, one setup for PLA and one for PET-G. That makes life easier as I don't need to mess with the different settings you need in the slicers. It was a fun project that took about 3 short days to print everything. Good luck if you decide to print one for yourself... Happy New Year!
