Ask for advice on how to solve the problem if you don't understand the structure of the hand board. Is it an inclined top? Look at this wall thickness is injection molding. How can the parting line and parting line be solved if they are not the same or even parallel?

Mould should be quite difficult to make

Does this work

Press your face with a torch every day, haha

Yes

This looks good

Be creative

This can also be done.

The brain hole is really big.
