Upgraded A1 mini Silent Enclosure 2.0 - The Perfect Low-Cost Solution for Dorms

The enclosure I shared previously was well-received by many friends, and this time I'm bringing a fully optimized second-generation version! It still adheres to the "just enough is good" design philosophy, enhancing stability and aesthetics while maintaining core advantages

✨ Key Features

Aesthetics++++++++++++
Material Saver King The entire structure only requires less than 1.41kg of PETG material (approximately 25 RMB in cost), saving over 60% compared to typical 2-3kg solutions on the market Through clever structural design, it achieves extreme lightweighting while ensuring strength

Zero Hardware Installation Completely discards hardware such as screws and corner brackets, entirely adopting a snap-fit design Although the initial installation requires a bit of force (gentle but firm is recommended), stability is absolutely no problem If any part is a bit loose, simply secure it with tape

Upgrade Added a solid modular power port for better sealed placement of power cables, not necessarily placed as shown in the picture, place it wherever you want

Fewer and more robust parts, making the overall structure more stable, placing Bambu Lab AMS on top is no longer an issue

Added door hinges, no need to find other files to print

The top can be expanded with cooling and exhaust modules

Precise Dimensions
• Overall: 500×420×500mm (Length × Width × Height)
• Groove depth uniformly 10mm, convenient for installing soundproof/transparent materials

• Side panels: 440×440mm
• Top/Bottom panels: 440×380mm
• Front/Rear panels: 440×380mm

🎨 Regarding Material Selection

• PETG printing is recommended for the main frame, and it is advised to enable silent mode to prevent tipping
• Upgrade: Tee connectors can be printed with PETG, preventing warping
• Use light-colored/transparent materials cautiously, as they may leak light with high-brightness illumination

🛠️ Practical Advice
• Sound insulation solution: Acoustic cotton costing around 10 RMB is sufficient (choose one with adhesive that isn't too sticky) For transparency, acrylic sheets can be chosen (40-50 RMB)
• Shock absorption pads can be added to the bottom, such as high-density acoustic cotton A whole piece is quite expensive, you can pool together for a few small pieces for the first order
• Ample internal space for large-capacity poop bin and tool kit

⚠️ Printing Precautions
Keep ambient temperature as high as possible to prevent warping, silent mode is recommended for all frame parts, and pay extra attention to preventing tipping with PETG material

This version optimizes structural stability and ensures smoother installation If you have needs for matching tools (such as integrated filament bins, cable organizers, etc), feel free to leave comments and suggestions, and I will consider designing expansion kits

Your support is my motivation for continuous optimization I look forward to seeing finished prints with various color schemes～
