Summary

  • Wall/ceiling mount bracket for ESP32 UWB Pro anchor — supersedes Rev A stem-collar design
  • 4-part parametric OpenSCAD system: backplate, articulating tilt arm, PCB cradle, cable clip
  • Adjustable tilt angle 0–90° in 15° detent steps (0° = ceiling/face-down, 90° = wall/face-out)
  • USB-C cable routing channel through tilt arm + exit slot in cradle back wall
  • Rear label card slot for printed anchor-ID strip (e.g. "UWB-A3 NE-CORNER")

Parts

STL export Description
uwb_wall_base.stl Backplate, 2× countersunk M4/wood-screw holes, pivot ears with 7-step detent arc
uwb_tilt_arm.stl Pivoting arm with M3 knuckle + detent plunger pocket, USB-C groove
uwb_anchor_cradle.stl PCB cradle, 4× M2.5 standoffs, USB-C slot, label window, antenna keep-out cutout
uwb_cable_clip.stl Snap-on arm cable clip, print ×2–3 per anchor

Hardware BOM

  • 2× M4 × 30 mm wood screws / #6 drywall screws (wall fasteners)
  • 1× M3 × 20 mm SHCS + M3 nyloc nut (tilt pivot)
  • 4× M2.5 × 8 mm SHCS (PCB to cradle standoffs)

Parametric overrides

  • TILT_DEG — per-anchor tilt (0–90°, 15° steps); override at export time
  • UWB_L / UWB_W / UWB_H — adapt to different PCB sizes

Test plan

  • Render all RENDER targets — no geometry errors
  • Verify detent arc: 7 notches at 15° steps on base ear inner face
  • Verify label slot dimensions fit 1.0 mm laminated card strip
  • Verify M2.5 standoff height + pattern matches ESP32 UWB Pro PCB holes
  • Print uwb_wall_base.stl, screw to test block, verify tilt detent feel
  • Print full set, assemble, fit PCB, route USB-C cable through arm channel
