This is a quick design I made in Tinkercad for a family member. It's a soft insert for their bench top vice to perform more delicate work.
It can be printed in PETG or TPU depending on how flexible you want it to be.
I used different amounts of perimeters and infill depending on the use.
PETG:
Layer Height: 0.2 mm
Perimeters: 4
Infill: 25% Gyroid
Supports: Yes - I did one without and it worked, but probably best to include them.
TPU:
Layer Height: 0.2 mm
Perimeters: 3
Infill: 10-20% Gyroid - depending on how flexible you want it
Supports: Yes - I did one without and it worked, but probably best to include them.
