First Model try, some feedback?

[sonarok 0]

Hi everyone,

i'm still waiting for my ultimaker but already started to learn a bit about cad tools and currently trying sketchup... i already have created my first model (a pen cap) that was exported as .stl and repaired via netfabb, i already uploaded it to thingivers (

http://www.thingiverse.com/thing:21386

).

would be really great to have someone that could review this model or maybe testprint it and give me some feedback about it (mistakes? how to improve it to get better print results, imposible layout, etc.)

what i can see so far is that something with the position seems to be wrong because it looks like the cap is flying on the thingivers screenshot.

thanks in advanced!

faces in the model that form a 'ceiling' under an over hang should have at least a 20* angle from horizontal, otherwise you need to print with support which adds post process time and ruins surface finish. this would include the wall half way down the bore, and the arms going to the center pin.

hi again,

thanks for the really fast reply and test print!

And also good point at the horizontal elements, makes sense that you always need an angle because the printer cant put the PLA on nothing (printing in the air ). I will fix up these points and hopefully my printer arrives the next days.
