Design rules
- Walls 1.0 mm or thicker; thinner flaps can tear
- Round internal corners so tears don't start there
- Drain holes of 3.5 mm or more in hollow parts
- Supports leave small marks on soft parts; mark the faces that must be clean

Questions
How soft is 80A?
Firm but bendable, in the range of a shoe sole or a hard rubber bumper. For softer parts, ask for Formlabs Elastic 50A as a special request.
Will it last like molded rubber?
It handles repeated flexing well for prototypes and low-volume parts. For parts that flex constantly in production, we can talk through molded TPU or silicone.
Can you print gaskets?
Yes. Send the gasket as a solid STL; a ring 62 mm across prices at the $7.00 part minimum.
