Hero Me 4010 Dual Fan Duct with Improved Nozzle Visibility
Please note this is only the 4010 dual fan duct and not the full collection of parts.
This is a remix of Mediaman`s excellent Hero Me Fan Duct Design. Many thanks Mediaman for creating the thing. I have found it really does improve prints, particularly with larger nozzle printing.
I did have some issue with thin walls when attempting to import the Tinkercad OBJ files (countersinks walls around part fan fixing holes) so I have created from scratch in Fusion 360.
In this remix I have:
1.Raised the connecting cross bar to allow a much clearer view of the nozzle.
2.Redesigned the duct outer shell so the thing now prints without supports.
3.Tweaked fixing and location boss to make a little more robust.
4.Revised part fan fixing counter sink holes to remove the thin wall issue.
1.Printed without supports, you may wish to insert a single custom support at the centre of cross rail to help bridging(see uploaded image) but prints OK without.
2.All prototypes printed fine without a raft but this should be considered if you do not have great bed adhesion.
3.Printed with Black PETG, 0.2 res, 30% infill with 3 perimeters.
Apologies in advance if there is a similar remix I have not spotted. I have not checked this thing against all the other Hero Me accessories. I do not use any form of levelling sensor, my main aim was to increase nozzle visibility.
Again many thanks to Mediaman.
