3 Ways to Build It
I have included print profiles for every type of maker. You don't need to be an engineer to enjoy this model.
⚙️ Print Profiles & Mobile App Compatibility
I have uploaded specific profiles (like A1 and A1 Mini) that use "print-by-object" for the absolute best quality surface finish.
However, MakerWorld restricts these profiles to those specific printers if you are trying to print directly from the mobile app.
(Note: You can still download the A1/A1 Mini "print-by-object" profiles and simply change the printer type directly in Bambu Studio on your desktop!)
👉 Using a different printer or the mobile app?
Select the "All Printers" profile! To make it universally compatible for one-click mobile printing, this profile is set to standard "print-by-layer".
1. The "Print & Play" (No Electronics)
- For: Desk decor lovers, miniature collectors.
- What it is: A fully printable version with a static "screen" insert.
- Effort: Low. Just print, snap together, and admire. No wires, no soldering.
2. The DIY Shell
- For: Makers who have their own code.
- What it is: A perfectly fitted housing for a 0.96" OLED Display and an ESP32-C3 SuperMini.
- Effort: Medium. Use it as a clean, screwless case for your own Arduino/ESP projects.
3. The Full "Smart Companion" (Highly Recommended 🚀) - 👉 Click Here for Detailed Overview, Firmware & Setup Guide
- For: Anyone who wants a functional device.
- What it is: Using my Open Source Firmware, this becomes a live internet-connected display.
- Effort: Easy! No coding required.
🚀 The "Smart Companion" Features
I have built a complete software ecosystem for this case. You don't need to write a single line of code — just plug it in and use my Web Installer.
- 🕒 Internet Clock: Auto-syncs time and date based on your location.
- 📅 Calendar & Holidays: Displays the current date alongside a full monthly grid and tracks national public holidays based on your country.
- 🌤️ Weather Station: Live Temperature, Humidity, and Forecasts (via Open-Meteo).
- 🍃 Air Quality: Monitor local AQI levels (US & EU Standards).
- ☀️ Daylight Info: Tracks sunrise, sunset, solar noon, and day length.
- 📊 Stock Tracker: Track market data for up to 5 global assets, ETFs, and Mega-Cap Tech at once with daily trend indicators.
- 📈 Crypto Tracker: Watch up to 5 of your favorite coins (from top 75 global cryptos) with price and trend indicators.
- 💱 Currency Tracker: Track exchange rates for up to 5 fiat currency pairs with custom scaling multipliers.
- 🖥️ PC Hardware Monitor: Connects via USB or Wirelessly to your Windows/Mac/Linux computer to show CPU Load, RAM Usage, and Network Speeds in real-time!
- 🎧 PC Media: Displays currently playing track, artist, album, and playback status streamed directly from your connected computer.
- 🖨️ Bambu 3D Printer: Local network telemetry for your Bambu Lab printer (progress, temperatures, fans, and print status) featuring smart layouts for Idle and Printing modes.
It is fully customizable! The device hosts its own Web Settings Panel (accessible easily via its unique .local domain name), where you can turn screens on/off, set up Smart Auto-Hide for inactive PC and Printer screens, and drag and drop them into your preferred order. You can also change transition effects (Slide, Dissolve, Blinds), fine-tune your precise city/country location, and set up Night Mode schedules to automatically dim, completely disable, or gracefully "dim then turn off" the screen while you sleep - all right from your phone browser!
Prefer desktop? The PC App lets you manage all of these settings right from your computer. It features a dynamic UI that physically rearranges itself in real-time to match your custom screen layout, and will automatically fallback to Wi-Fi if you unplug the USB cable!

👆 Touch Button Controls: If you install the optional touch sensor, you can tap to instantly skip screens (or wake the display from Night Mode), and use the new Long Press feature to lock/unlock auto-rotation so you can keep your favorite screen visible indefinitely!
🛠️ Hardware Needed
For the electronic version, you need less than $5 worth of parts:
- ESP32-C3 SuperMini (The brain)
- 0.96" OLED Display (I2C protocol)
- 4 Wires (Silicone or Jumpers)
- (Optional) TTP223 Touch Sensor (For tap-to-skip and long-press screen locking)

⚠️ Important Note on the 0.96" OLED Display
 |
The physical width of these screens can vary slightly depending on the manufacturer.
I designed this case around a very common variant (~26mm wide - see attached photo) with quite tight tolerances.
Most displays you find online will fit perfectly, though you might need to apply gentle force to snap it in.
However, if you measure your display and it is noticeably wider than 26mm, or if you already printed the case and it simply doesn't fit - don't panic!
Based on feedback from other makers, simply scaling the 3D model up to ~105% in your slicer works perfectly.
🖨️ Printing & Assembly
- No Screws Required: The case uses a precision snap-fit rail system.
- Support Free: The "Main Body" prints upright with no supports. The "Cover" needs minimal standard supports.
- Orientation: Print exactly as oriented in the profile for the best surface finish.
📦 Software & Setup Guide
I have created a dedicated project page with a One-Click Web Flasher and a detailed step-by-step guide.
This project is 100% Open Source. You can view the code, contribute, or modify it on GitHub.
If you print this, please post a photo! I love seeing these little guys on desks around the world. ❤️
