Probably not too complex. The real problems are when the part has to have certain physical properties that the cast material isn't capable of. A cast plastic part might not have the strength or durability needed. Or the real parts need to be food safe plastic or dishwasher safe. If the part isn't performing any difficult physical need then it would probably work just fine.so it has "teeth". Could it be too complex for that production method ?
Xoemetry says they can give instant quotes for urethane castings and other processes. I've never used them, but I did use Fictiv to injection mold 3 covers and a spacer for my production parts. When you upload the parts, it will give suggestions as to what geometry in your model may make the mold more expensive (needing slides and lifters to product mold). The molds weren't as expensive as I was expecting them to be.
