Netgear ReadyNas Duo Hard disk tray.
I printed in ABS as i doubt that PLA will handle the heat from NAS, but you can try.
Support is needed only on the place where the handle attach to case with the screw.
The screw is 3mm in diameter
The clamp is not printed but cut from a sheet of metal of 0.5mm - 2mm height, as reference i cut mine from a old CD unit case using a dremel.
Body is printed with infill of 20% and the handle with infill of 50%, also i used gyroid infill.
The Nas is model RND2000 hardware version 2 but shouldn't be any problem to use on v1, NV+ or ReadyNas Duo v2
