I picked up a compact turbo fan from AliExpress, but the cardboard box it arrived in wasn’t quite up to my standards.
Since it came with a decent foam insert, I repurposed the original tough box and redesigned it to properly suit my needs.

Final dimensions:

This is a box with the internal dims of 170x120x40mm

• .28mm layer height (didnt see the point of a super file qulaity. its still comes up great.
• printed with no supports
• change the colour of the latch and the text to suit 
• wall loops of 5
• sparse infill dettern and density is honeycomb and 15%

Extra parts to build

6x M3 bolts @30mm long

I get these from Aliexpress
