Please let me know your results if you print it!

I designed this case to be a mini ITX pfSense router containing a discrete Intel NIC, an SSD and a slim 12cm fan.

It's quite neat and very easy to put together - only 2 halves that slide together - the front and the back!

Small printer friendly - each half footprint is approx 20cm x 8.6cm and height 11cm for the taller half.

Great as a small factor desktop, home theatre PC or a router/firewall.

The motherboard and NIC together slide into grooves, and are quite sturdy.

The the locking tabs might need some tweaking.

In my original V1 design, the tabs snapped off but the case is still usable. Since then I improved the design but haven't printed the new version myself so let me know your results.

It also has holes in the back for 2x SMA headers if you need to run a wifi module (may need to enlarge these - I didn't end up using them so can't comment on fit).

It's designed to fit a standard mini ITX backplate, so in theory any motherboard will fit provided the heatsink isn't too tall and the Pico PSU has clearance.

I used a 16mm LED push button as a on/off switch (overkill but looks nice).

Gelid Slim 12 UV Silent 120mm (overkill but the Intel NIC gets hot. It comes with a speed resistor, and is very effective. Silent and cool.)
