Description

A compact two-piece case with a vintage Bakelite silhouette: rounded corners, softly drafted walls, and a clean split line between the lower housing and the upper cover. At 120 × 65 × 28 mm, it gives a small board or module a protected home, with a hollow internal cavity, four corner screw bosses, reinforcement ribs, and a tongue-and-groove closing lip. The enclosure prints as two separate pieces, with the cover laid beside the housing so both print without supports.

Design notes

  • Lower Housing: the deeper shell, with corner bosses, internal ribs, and a raised closing tongue.
  • Upper Cover: the lid, with a matching groove and clearance holes for the screws.
  • Walls and corners: 2 mm walls, 8 mm outer corner radius, and a 1.5° draft on the outer shell and lip.
  • Screw bosses: four corner bosses with 2.6 mm pilot holes in the housing and 3.2 mm clearance holes in the cover.
  • Printing: separate upper and lower parts, oriented to avoid supports.
