Snapmaker J1 Cooling Fan Upgrade Kit – Convert to J1S

Your PLA prints are lumpy, overhangs look rough, and you're pulling the top panel off every single run just to get clean layers. This upgrade kit fixes that. It drops the ambient temp around the print bed, cools parts during high-speed printing, and keeps your J1 running without the panel-off ritual. Narrow fan duct design means directed airflow, less turbulence, cleaner results. Install it once. Stop fighting the heat
