3D printed RC plane cowling

[dles]

Greetings to all!
Recently I bought 3D printer, so I am designing and printing some stuff for my house and hobby (building and flying RC planes).
Until now in all my projects, I had (at least two) perpendicular sides. Now I am trying to draw (and print) a cowling for my RC plane. I designed top and bottom sides (which are not perpendicular), and plus all side surfaces should be rounded, and I do not know how to draw those sides, so I would appreciate a help/tip/advice…
I am using SketchUp Make for all my projects.

Thanks,
Darko

I am trying to model and print something similar to this:

Looks Good In Sketchup Very bad in .stl file

I am new to both SketchUp and 3d printing. (about 5 weeks now) This is my first complex part and after working through the several tutorials from Trimble and others on Youtube I was pretty proud of this part! It looks pretty nice in SketchUp but when I get it into the slicer software and print it it’s a different story! I am willing to bet way down in some pull down sub-menu there is EXACTLY the thing I need to fix this in one click though! I am going to post several images so you can see w…

I have reached my skill limit

This is not saying a lot! I have finished the plane but I am stuck on this part! I have failed a LOT. I am trying to make a windshield that curves in every plane! This piece will be the removable battery hatch of the RC plane so it is the “hood” and the windshield of the airplane in one piece. (Curviloft whooped the “hood” just fine) I am trying to merge multiple parts and do an “intersect faces” to get the windshield formed and merged into the ‘hood’ I cut these parts out in…

Blatant Show Off Post! (Or Sketchup Marketing!)

I have to say I am pretty proud of myself but I also think this is a great SketchUp testimonial! Two months ago I decided to learn CAD. I wanted to 3D print and not other peoples creations. For the first two weekends I tried several CAD Packages. The first weekend I started with the Free ones- LibreCad and Blender. I think the brain hemorrhages are almost cleared up now because they seriously made my head hurt. The Second weekend I tried the TurboCAD free trial because if I liked it the home…

Hi Anssi…

I really appreciate your help. Thank you very much for instructions…
This tool and topic are amazing: I completed my cowling within an hour…
Happ like a little baby…

Thnak you once more and regards,

@dles

I completed my cowling within an hour…

I’d love to see an image of the resulting model (and/or a printed part)!

Hi TDahl,
Thank you for showing an interest.
Please find sketchup file. I just put model to print, so will see tomorrow does it fit and how it looks like on the plane…

Best regards,
Darko

Looks a good shape, but all of the higher faces are reversed (shown in blue-grey).

That will technically make it not a solid (in SketchUp terms) and depending on how tolerant your 3D Slicer software is, might cause it not to print.

R-Click on a white face in SU and choose Orient faces.

Or install the plugin Solid Inspector 2 from the Extension Warehouse, to check for other features that might make a model not a solid. (Reversed faces were the only problem in this model.)

Hi John.

Thank you for a gret tip: I installed Solid Inspector 2 and fixed it in a minute…
Actually, I was wondering why this top object is in blue-grey and now I know why: reversed faces.

Regarding printing: object is still printing but it seems that Cura did a good job, it seems that it will be printed correctly…
I am relatively fresh in 3D printing. Until now I did not have to take care that objects needs to be manifold. For sure I will learn a lot and thank you all for that…

Best regards,
Darko
