Manta MK2 Duct & Tool Head System

Update: 05\04\22 Replaced: WIP_Direct Drive Head Ender 3 Orbiter V2 no Upstand V2_1 as the original conflicted with the mounting plate.Update: 25\01\22 The V1_1 Orbiter Mounts had incorrect fixing centres for the V1.5 Orbiter so I have uploaded V1_2 (+ step files)for both tool heads to correct this error.Update: 12_01_22 Uploaded Tool Head mounts for the Orbiter V2 Extruder. They are both definitely WIP, I do not own a Orbiter V2 and are based on the CAD models.Update:18\10\21 Uploaded some 5010 fan ducts which are 8.5mm longer to allow for a Volcano Hot End. These are definitely WIP. I have not printed, installed or produced any CFD simulations at this time. The parts are extended at the duct so the standard base and support arms should work with these parts. I stress very much work in progress.Uploaded images of CFD simulation testingUpdate:31\08\21 Noticed a very very slight discrepancy with the Duct Base for the V1 hole centres, only 0.15mm which the hole tolerance should allow but
