Ultra-low-cost AWTRIX Frame

Summary

A compact, professional-looking AWTRIX display you can build for a fraction of the original cost. This project provides STL-ready parts and a step-by-step 3D-printing and assembly workflow so you can create a sleek 32×8 WS2812B pixel display housing with interchangeable covers and a clean diffuser. Ideal if you want a customizable smart-home information display that looks polished on a shelf or mounted to a wall.

Thing Details

• Complete set of 3D models (STL) and a detailed printing & assembly guide to build a full AWTRIX frame.
• Designed to fit most common FDM printers (minimum bed ~175 mm).
• Low-cost build: base parts ~ $20, full feature set ~ $25 (electronics not included in STLs).

Key features

• Fits 32×8 WS2812B LED matrix and ESP32 dev module
• Interchangeable covers for color/texture customization
• Semi‑transparent diffuser for crisp pixels and near‑black off‑state
• Multiple mounting/placement options: wall, standing, or lying
• Optional add‑ons: light sensor (LDR), DFPlayer Mini, buzzer/speaker

Print Settings

• Filament Material:
  • PETG for most structural parts (base, covers, button mounts)
  • Semi transparent PLA for diffuser (best diffusion and finish)
  • TPU for anti‑slip pads
• Supports: No
• Infill: 20% Gyroid
• Orientation:
  • left/right cover: print upside down (face on built plate)
  • Pushbutton parts: try out which orientation works best for your printer
• First/Top layers: Hilbert curve pattern recommended (if supported)
• Surface finish: Optional "fuzzy skin" on outer walls for a textured matte look

Assembly

• Diffuser: Print with finer layers. Wipe clean and remove strings before assembly.
• Test fit: Dry‑fit parts before applying screws or glue. Sand mating faces if fit is tight.
• Screws: Clear holes of debris and use low‑profile flat‑head screws to sit flush.
• Optional acrylic: If using semi‑transparent acrylic, cut to size and test fit before final assembly.
• Anti‑slip pads: Press‑fit or glue into recesses (use adhesive suited for TPU or the base material).

Full wiring diagrams, flashing instructions and the AWTRIX software (apps) are documented in the GitHub project.
