TPU 98A
Buse : 0.4 mm
Wall : 0.8 or 1.2 mm
Infill : 10%
2 versions : 1 thick (3.5 mm) 1 thin (2 mm)
The idea is to create a soft material with the infill in order to absorb all impacts.
I will be interested if you try with another material (eg TPU 85A)
If you do not have a samsung s9 and want a case for your phone, feel free to contact me. Depending on the phone I would try to design one for you ;)
Bye :P
