Before you print
Open enclosure; no lid. Fixed body 120 x 80 x 36 mm with 3 mm walls/floor. Four 10 mm posts, 8 mm tall, on a 90 x 50 mm pattern, with 3.2 mm blind pilot holes. Eight 3 x 14 mm vents. Overall width with ears: 164 mm; two 6 mm mounting holes on 144 mm centers. Front window starts 10 mm above the base. Print base down; inspect port bridging. No waterproof or thermal rating. Geometry has been digitally checked; this template has not been physically test-printed.

Create an editable, single-solid controller enclosure in Nora3D, in millimeters. Use a new owned document. The base lies on XY and height follows +Z. Build a 120 x 80 x 36 envelope centered in X/Y; subtract a 114 x 74 cavity starting at Z=3 and opening through the top. This leaves a 3 mm floor and walls. Keep the box open: this recipe does not include a lid. Add four cylindrical PCB posts, radius 5 and height 8, starting on the floor at (X,Y)=(±45,±25). Cut radius-1.6 blind pilot bores from Z=3 through the tops of all posts, leaving the floor intact. Add two mounting ears centered at X=±70,Y=0, each 24 x 26 x 4, and merge with the housing. Cut 6 mm diameter holes at X=±72,Y=0. The finished ear-to-ear width is 164 mm. Cut eight 3-wide, 14-high slots through the rear wall, with centers X=-35,-25,-15,-5,5,15,25,35 and lower edges Z=12. Add a centered front connector opening, initially 20 wide and 12 high, lower edge Z=10. Add a circular port through the right wall, centered at Y=18,Z=20, radius 4. Resolve actual native axes before orienting the port tool. Expose only connector width 16–30, connector height 8–16 and side-port radius 3–6. Keep posts, ears, wall thickness and vent layout fixed. Name the contributing features clearly. Verify one solid, open cavity, blind post bores, wall penetrations, mass against the analytic construction and strict save/reopen. Test all eight parameter corners, default and midpoint; check the downloaded STL, not only the viewport. No waterproof, thermal or load rating is claimed.
