HDD adapter - 2,5 to 3,5 for 8pcs HDD in 3x5,25'' bay

I needed to add as much as possible HDD to a home server so I made this adapter to add 8x 2,5'' drives to a 3x 5,25'' drive bay.

It is designed so it can hold drives up to 12.5mm hight and drives can be either just placed in place or you can use screw if you want to but it isn’t necessary.

Drives are put in zig-zag fashion so you can have place for SATA power and SATA data cable.

At front is place for 12cm Fan to cool all drives.

Adapter is designed to be easily printed without supports.

I've added gcode for 0,2 layer height, but there is no angle greater than 45° so it can be printed without support even on draft.
