When designing copper parts, keep these best practices in mind: Maintain a minimum wall thickness of 0.5 mm. For CNC milling, think about using parts up to 1200 x 500 x 152 mm in size, and for CNC turning, parts up to 152 x 394 mm. For undercuts, we suggest square profiles, full-radius, or dovetail profiles.
