Hard disk, CD / DVD drive rails

This is from a 10+ year old Fujitsu workstation with the Intel i975 chipset. Not sure if the adapter is generic enough to fit others, but feel free to try. The print time for 2 HDD rails (one set) is about 1.5 hr on 0.2mm layer height.

[Note] I have not printed the CD / DVD rails myself. It was modified from the HDD rail design and should be ok in general.
