🔥 Bambu Lab A1 Cooling Mod! Add a Motherboard Fan for Enclosed Printing | 3D Print Upgrade Guide

⚠️ Running your Bambu Lab A1 inside an enclosure? Then you need to watch this! In this video, I show you how to add essential cooling to the A1 motherboard, something Bambu surprisingly left out on this model — unlike the A1 Mini.

I walk through the full mod process, including:

✅ 3D printing a custom fan mount
✅ Using SolidWorks to design a perfect shim adapter
✅ Choosing the right 40mm 5V USB fan
✅ Step-by-step installation and cable management tips
✅ Why airflow is critical in enclosed setups

💨 This upgrade is perfect if you're printing in an enclosure for VOC control, pet safety, or better print consistency — all without risking an overheated motherboard.

⚙️ STL files and Amazon links are in the description below so you can replicate this setup easily. And yes — you can power this off a USB port. No wiring hacks needed!
