Design Do’s

Design Dont’s

Maintain   uniform wall thickness

Core out   thick areas

Design with a   flat surface, lettering and threads

Consider   location of gates, ejector pins, and parting lines.

Walls should   be no thinner than 0.1mm (0.0039 in.)

Don’t design   holes smaller than 0.1mm (0.00e9 inc) in diameter

Dont design   components over 12.55 mm (0.5 in.) thick and over 100 grams in mass

Avoid   designing sharp corners
