FixtureAI Review
enclosure.sldprt
Wall thickness is 0.8 mm, below the 1.2 mm minimum for ABS injection molding. Thin walls cause sink marks; increase it for a reliable fill.

Frequently
asked questions
A senior engineer,
reviewing every move.
Embedded in every problem, FixtureAI flags what textbooks skip (manufacturability, tolerances, design intent) and explains every fix so it sticks.
Two things before this is production-ready:
The bolt bosses have no draft. Add 1.5° so it ejects cleanly.
Uniform 3 mm walls, great for even cooling.
