MarkNAS

A NAS enclosure with the same mechanism as the Feiniu EVO2 but with an additional 3.5-inch hard drive bay compared to EVO2 so it is slightly larger than EVO2 in size A1 mini printable

The motherboard is a Changwang 9*9 mini small motherboard I am using the P6-N200 The hard drive backplane is Brother Shuangqiu's 3-bay backplane To reduce the volume of the back cover I found a Xianyu seller to customize it and adjusted the direction of the connectors

There are only four parts in total

1) Case body no hard drive caddy needed hard drives can be installed directly with anti-vibration screws

2) Back cover a fully enclosed back cover unlike a direct airflow duct structure this uses an 8-9cm blower fan

3) Front cover honeycomb panel just set the top and bottom thickness to zero

4) Motherboard bracket uses Changwang's 9*9cm small motherboard fixes the motherboard and fan

When opening with Bambu Studio choose not to combine into one part drag to different plates to print

A size comparison with Feiniu EVO2 is shown in the figure below
