Minimalistic and easy to print folding feet for laptop rear side elevation and better air flow.I designed them for my Lenovo ultrabook 720s which is very thin, powerful, but super hot when processor is moderately loaded. Feet are 5mm thick when folded, which is 1mm taller than stock rear elevated pad. When unfolded the rising is 30mm - good enough for much better ventilation.
Parts can be printed as is together, then use metal rod made from standard paperclip - cut 20mm long piece and connect two parts. Then use strong 3M double-side adhesive foam to connect base to laptop as shown on pictures. Hint: flatten about 1-2mm of metal rod end after inserting it, then press that flattened area in - it will keep the rod securely in place.
It's currently V1 and requires some testing. Feet hold folded position but are loose when unfolding, need to add some sort of lock for that position.
