DFM Tips

1. Use standard hole sizes

   Prefer 3/4/6/8/10 mm or #/letter drills; call out tolerances only where needed.

2. Avoid deep, narrow pockets

   Keep depth ≤ 3× tool diameter; add reliefs for internal corners instead of 0-radius.

3. Consolidate setups

   Symmetry and common datums reduce fixturing and error stackup.

4. Specify finishes by function

   Cosmetic faces → bead blast / anodize; bearing surfaces → as-machined + tolerance.

5. Thread strategy

   Use inserts for soft materials; call out thread depth and start side.
