CAT S60 smartphone shell case. Max open. Thick back.

Very simple CAT S60 smartphone back protecting case which has thick wall.

Initially created to protect the camera lens from finger prints and scratches.
So you can just put the phone on any workbench surface without fear of delicate plastic camera lens catch the unrepairable damage.

In the same time sides are open for better buttons and ports access. Therefore this case will not protect from high drops.

This design is EXPECTED to bend or even break when it falls vertically. it is done on purpose so CAT S60 will have less damage.

Print with 0.2 mm layer height for better strength.
0.3mm works as well, but I do not trust this print )))

Do not print with soft plastic cause design will not hold its form enough to keep the smartphone inside firmly.
Do not use the low temperture plastic cause CAT S60 can heat significantly when it is in poor mobile network conditions and experiencing heavy CPU load in the same time.
