Builder BigBuilder (Original) enhanced fan duct replacement

Description

This Is The Story Of A 3000€ Printer. Https://Www.3Dhubs.Com/3D-Printers/Big-Builder-Dual-Feed-Extruder It Has Great Framing, Great Rods, Great Extruders, Great Volume, Great Precision, Great Mixing Solutions, And Then... 1 ) An Optional, Not So Great Hot Bed Whitout Sensor, Allright. 2) Only One Duct On One Side Of The Head For A Printer Of That Size? No Possible Upgrades? Years After Release? Happy That I Bought It Second Hand At Less That Half The Price, Else, I Would Be So Pissed. It Is Not Passing The Marvin Test. Can You Imagine? So Here It Is, This Is The First Working Version Of This Little Project To Replace The Original Duct (Keeping The Same Fan, At The Same Position) With One Doing A Better Job. Printing Marvin With It Was A Success, Including The Hook. Http://Www.Thingiverse.Com/Thing:215703 Feel Free To Improve It, There Must Be Room Left For It. Source File Included. *Update* After Two Days, I Can Already Say: Avoid Pla Unless Your Duct Fan Is Always On, Else, Above 200° It Will Bend Down To The Plate In +- 40 Mins. Abs Is The Way To Go (If Not Obvious...). Please Write Down Your Comments If You Print And Test It, Thanks!
