Anet A2 fan duct

Anet A2 Doesn't Get Much Love from Designers, So I Made a Fan Duct for It. It's For 50x50x15 "Turbo" Style Layer Cooling Fans. My Fan Is the Cheapest One I Found on Aliexpress; The Wires Were Too Short, Had to Extend Them. If You Have a Choice, Save Yourself the Headache and Buy a Fan with Long Enough Wires (90cm?). In the Latest Version, I've Beefed Up the Mount Plates and Enlarged the Lower Holes for the Hotend Fan to Make Inserting the Screws Easier. Use Original Hotend Fan Screws for Mounting, as This Thicker Version Won't Keep the Original Grille (Need 2mm Longer Screws If You Want to Keep It). You'll Need Two M3x20 (or Slightly Longer) Screws and 2 Nuts to Fix the Layer Fan, Plus the 5015 Layer Fan Itself. I Added a Version with an 18mm Autolevel Sensor Mount, Tested and Works. WARNING! v12 and Earlier Versions Are Quite Low and WILL Crash into Binder Clips If You Use Those to Secure Glass onto Your Bed, So It Will Reduce the Usable Area of Your Glass Significantly. V14 Is Raised by 1.5mm and Clears My Binder Clips. V15 Is the Same as V14 but Without Sensor Mount. Printer Settings Printer: Anet A2 Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 100% Notes: Try Printing This on a Raft, Especially If You're Doing This on a Stock A2 and Have "Elephant Foot" Issues. Without a Raft, the Bottom Layers on Stock A2 Can Get Squished Together Due to Z Mount and Coupler Flexing, Causing Cooling Holes to Become Too Small or Even Blocked. If You Have Problems Separating Rafts from Prints on Your Printer, Print Without a Raft. I Printed Mine with 1.6mm Walls, 100% Infill. The Non-Sensor Version Prints Ok Without Supports, Not the Prettiest Thing but Functional. You Need Supports (Only from Build Plate!) for the Sensored Version. V9 Has Stronger Mount to Hotend Fan. V12 Has Sensor Mount and Improved Access to Mounting Screws. I Printed the Sensored Version in PETG; For Previous Versions, I Used PLA. Both Work. How I Designed This I Used Sjouke's Ring Design and Created Everything Else. The Layer Fan Is Positioned Downward a Bit Not to Restrict Airflow to Hotend Fan Too Much. The Cooling Fan and Mount Don't Crash into Mainboard Mounts, So You Get Full X Travel.
