Mean Well LRS-350 Lid for 120mm Fan

Cover compatible with Mean Well's LRS-350 and other PSUs sharing the frame (such as some other LRS-series supplies), as commonly seen on Creality's Ender 3s and other similar printers

Uses the original mounting screws and holes, and can be installed without heat-set inserts. The 120mm fan can be installed with either M4 bolts from above, or self-tapping PC fan screws from below, albeit the latter does require some force to get the screws in place, so I recommend use of a socket wrench

Fan pictured is an Arctic P12 Silent, and I have also tested this cover with Fractal Design Silent Series fans

Split Version

While the full lid can fit on an Ender 3 print surface with careful positioning, for smaller printers i have included split STLs such that it can be printed in parts. A fan riser is also included, unnecessary for the full version, but i recommend it as reinforcement and a glueing surface for the split version, as the seam between halves can be a weak point

Print Details

The lid can likely be printed in most materials, however these are the details for the pictured example:

• Filament : Fiberlogy Easy PETG Black
• Layer Height : 0.2mm
• Supports : None
• Printer : Custom cartesian, Ender 3 V2 frame
