Don’t forget thermal stability either. The coefficient of expansion of ABS is about 4x that of aluminium.
I think 3D printing is a great prototyping tool but after using spectrographs with rather poor and excellent stability (LHIRES and ALPY respectively) I look for the highest stability possible in the design and construction of a spectrograph.
