bearing housing 3d model

Design a circular bearing housing for a 15 mm outer diameter, 5 mm thick bearing. The housing must include a precision bore sized for a 15.00 mm OD bearing with a total diameter tolerance of 0.005 in (5 thou), allowing up to 0.127 mm clearance. The bore depth should fully accommodate the 5 mm bearing thickness. At the rear of the bore, include an internal shoulder to axially support the outer race, creating a positive stop so the bearing seats against it. Behind this shoulder, the housing must have a fully solid back wall (no through-hole), making the rear completely closed. The front side remains open for bearing insertion. On the front face, add six equally spaced M3 threaded holes arranged on a circular bolt pattern around the bore at 60° intervals, intended to secure a retaining plate that captures the bearing from the front. Ensure adequate wall thickness (minimum 2–3 mm around the bore) for structural integrity, and apply light chamfers to exposed edges.
