<p>This is my design of a blade rack for Odroid h2 <a href="https://www.hardkernel.com/shop/odroid-h2/">https://www.hardkernel.com/shop/odroid-h2/</a>.<br/> It is 4U high including about 1cm above and below for airflow, each bay has a 40mm fan, I used (<a href="http://www.fractal-design.com/home/product/casefans/silent-series-r3/silent-series-r3-40mm">http://www.fractal-design.com/home/product/casefans/silent-series-r3/silent-series-r3-40mm</a>), spacing of fan holes should be 32x32mm.<br/> It will host 7 Odroid H2 units. In future releases I might replace one of the bays to mount power supplies for the fans and maybe the H2's.<br/> I use them for virtualization with Ovirt (<a href="http://www.ovirt.org">http://www.ovirt.org</a>).<br/> Blades are designed to use hardkernels power button (<a href="https://www.hardkernel.com/shop/led-power-button/">https://www.hardkernel.com/shop/led-power-button/</a>).</p> <p>Bay Parts<br/> Bay.stl 7<br/> Bay-Cable-Holder.stl 7<br/> Bay-Slider.stl 14<br/> Bay-Tag.stl 7<br/> Bay-Tag-1.stl Used for MMU printing with Bay-Tag.stl<br/> Bay-Tag-2.stl Used for MMU printing with Bay-Tag.stl<br/> Bay-Tag-3.stl Used for MMU printing with Bay-Tag.stl<br/> Bay-Tag-4.stl Used for MMU printing with Bay-Tag.stl</p> <p>Blade Parts<br/> Blade-Base.stl 7<br/> Blade-Back.stl 7<br/> Blade-Bottom.stl 7<br/> Blade-Front.stl 7<br/> Blade-Top.stl 7<br/> Black-Lock-Peg.stl 7<br/> Blade-Lock-Button.stl 7<br/> Blade-Lock-Button-1.stl Used for MMU printing otherwise<br/> Blade-Lock-Button-2.stl Used for MMU printing otherwise<br/> Blade-Lock-Button-3.stl Used for MMU printing otherwise<br/> Blade-Lock-Button-4.stl Used for MMU printing otherwise<br/> Blade-Tag.stl 7<br/> Blade-Tag-1.stl Used for MMU printing otherwise<br/> Blade-Tag-2.stl Used for MMU printing otherwise<br/> Blade-Tag-3.stl Used for MMU printing otherwise<br/> Blade-Tag-4.stl Used for MMU printing otherwise<br/> Blade-Tag-5.stl Used for MMU printing otherwise<br/> Blade-Tag-6.stl Used for MMU printing otherwise<br/> Blade-Tag-7.stl Used for MMU printing otherwise<br/> Blade-Tag-8.stl Used for MMU printing otherwise<br/> Blade-Handle.stl 14</p> <p>Rack Ears<br/> Rack-Ear.stl 2 (They are symmetric so just flip them around no need to flip in slicer)</p> <p>Hardware<br/> 4pc M4 threaded rods length 440mm<br/> 8pc M4 nuts and washers</p> <p>Each blade requires<br/> 8pc M3x10 Countersunk<br/> 6pc M3x5 Not Countersunk<br/> 2pc M2.5x?
