How to print that as best, accurate and save as possible?

Motor_cover2_edit.STLHi guys,
i want to print this big 3d-cover... however if i use support, it needs way more time and material, and often with support, it doesnt look that pretty...
Do you think it can be printed without support? How would you print it, as it is or rotated 180° "on head" ?

Its a part of this project "https://www.thingiverse.com/thing:4314214" - since this part is visible i want to have it as beautiful as possible - and i have to print it over night, so I dont want to have a big mess in the printer on the next morning.

best regards,
Fabian

I would print it as is :

You don't need much support, so I would give it a try to print without support.

Do you think the top can be printed without support? Or will this collapse at the end of the Print?

The infill will protect the top from collapse.

 

Support goes on the outside to help print things that stick out. There is only the ring on the side of this part that is effected but because of the shape and it doesn't stick out far I think it should be fine without support.

thank you - in regards to infill he gave the setup 30-50%, which one would be saver for no support print? 50? or more?
Same question for profile (layer height) - 0.1mm (21h) or 0.15mm (7h)?

I normally don't add more infill then 30%, I normally stick to 20% and if i want a part stronger I add more walls and top/bottom surfaces.

The inside is hollow, but I am still think it will be possible to print without support. But you can only try it....

good morning,
it came out amazing - its 0.15layer height, 30% infill, no support.
just pretty small failures under the ring, but in general im more then happy. Used ABS for that.

Thanks for the support.
