I appreciate your support. Enjoy DIY
A compact, ESP32-powered accessory designed specifically for the Bambu Lab A1, A1 Mini 3D printer. It replaces the original hotend faceplate with a custom 3D-printed enclosure (the "Box") that houses a vibrant 2.4" touchscreen display.
WORK BOTH 2.4" and 2.8" Resistive Touch Screen
📡 Live Status Display
PrintpooP connects to your A1 via Wi-Fi and presents real-time print data —such as print progress, temperatures, fan speeds, and Clock —right at the print head. This localised status view makes monitoring more intuitive and visually engaging.
🎮 8-Bit Aesthetic
All visuals are styled in charming 8-bit pixel art, giving your printer a retro personality. Animations and icons are custom-designed to blend nostalgic design with functional UX and sound effects.
Choose between two adorable themes: a playful Kitten or a loyal Puppy to accompany your printing journey!
🛠️ Easy Mounting
The enclosure is engineered to replace the Bambu Lab A1's default hotend faceplate, securing PrintpooP in a clean, integrated form factor.
For the USB power supply, connect to the AMS extension port. Recommend this project https://makerworld.com/en/models/1469000-double-usb-a-power-port-case-for-ams-port#profileId-1532992

Page 1 - PrintpooP in action (displays a cute kitten or puppy for each print stage) - After one minute of inactivity, trigger a "PrintpooP" swinging animation for the idle state.
- After one minute of printing, initiate a "PrintpooP" swinging animation that follows the print head's movement.
(This animation needs an MPU6050 gyro sensor attached as an option. The other functions work normally without this sensor.)
