// RemoteRig camera node case v4
|
||||
// Parametric OpenSCAD prototype for a status-panel camera node enclosure.
|
||||
// Units: millimeters. Coordinate system: X=width, Y=depth/front-back, Z=height.
|
||||
// Front/service lid is on the -Y face. Rear strap channels are on the +Y face.
|
||||
//
|
||||
// Prototype assumptions to confirm against purchased parts:
|
||||
// - 1.3 inch OLED module/window opening: 31 x 16 mm visible window, 35 x 19 mm panel clearance.
|
||||
// - Small rocker switch cutout: 13 x 19 mm rectangular snap-in opening.
|
||||
// - LEDs: two 3 mm panel LEDs (PWR + RGB STAT) with 3.2 mm holes.
|
||||
// - Boards: ESP32-C3 Super Mini 22.5 x 18 mm, ESP-01S 24.7 x 14.3 x 12 mm.
