This is an SSD/HDD tray for the CoolerMaster HAF X 945 case in 2 versions.
This is the normal tray, with SATA and power connections oriented from the back, like in original HAF trays.
This tray is somewhat different from the original one. Here, the SATA and power connectors are oriented from the front instead of the back. It's done this way on purpose, so that removing disks can be performed without touching the second case wall. Original trays require the user to unscrew both walls before doing anything with the disks.
The photos show how the trays look like when they're installed in the case. Screw positions should work for all HDDs and SSDs. Please note that there are no "alternate" positions of screws for newer Western Digital disks, simply because I don't have such disk.
The drawings are done in BricsCAD, maybe the DWG files will be loadable in AutoCAD, but I'm not sure.
Just load in CURA and print ;), no supports needed, you just need to properly orient the part.
Printing time: ~4.5 hours with 0.1 layer height (on my printer).
