This is design of hot swap for full size 3.5 inch with 2.5 inch tray HDD for internal pc cd-rom slot (FOR STANDARD CD-ROM PLACE).

Fits my pc case - may be different with other cases but should be similar i think. There are three packages STL, 3MF, and photo files . 3D packages have 14 files without photos. The photos show how it is supposed to be put together and what it can do. Besides, there is a video on YOUTUBE where I show how to assemble the case and how not to assemble it (I think I made all the mistakes I wanted to avoid, but it was my first video on YOUTUBE :) ).

I received sata cable connectors bent in all directions (in a place covered with hard rubber - shown in photo - inaccurate cast), so I decided to design and replace it.

FIRST TWO WAS PRINTED WITHOUT KLIPPER ON E5 PRO with merli 2.0.6 AND THEY ARE SITTING IN MY PC :)

Printing time (all parts) was about 20-24 hours (That was tests-I can't say exactly)

All Files are exported in position that they were printed, the choice of adhesive layer is yours ).

There is need to have 7 skrews 3.5x9.5~9mm shown in the video.
