Shell, or not??

Post by Rootz » Wed Jun 12, 2013 8:30 pm

Hey Guyz,

I'm trying to print one of the whistles on Thingiverse with the Up! Mini but just don't seem able to get the body of the whistle completely hollow. I've tried Up! v1.18 and ticking the "shell" box but to no avail. Any idea what I might be doing wrong?

Cheerz!

Hi Rootz,

Shell won't work as the part is already hollow. Problem is the UP always wants to put support in, even though in some cases it's not necessary.

There is a whistle design that does work on the UP, but I don't know which one it is. Hopefully someone else will chime in with a link to it.

Ah! Thanks for letting me know.

So, there's no way around it, other than to scour Thingiverse or design a two-part whistle myself?

Ho hum! :?

You might try rotating the part so there are no horizontal flat surfaces, rotate 45 in X and Y, otherwise the flat surfaces will trigger support.
Then set "support Angle<" to "10 Deg" and set the "Support Area>" to "20 mm2" to reduce the possibility of support down to nothing.
Set to "shell and print.
You will have more possibility of outside support but that is easy to remove.

I previously posted a picture of the 2 tone whistle somewhere but now I will post the up3 model already rotated. Print with lowest support settings (10 deg) and preferably 2 whistles at a time or the heat of the nozzle will warp the top. With 2 to print the nozzle will move from 1 to another and the top has time to cool (this a good tip for all ''small'' models).

So here is the model (it's a zip because up3 is not allowed :o ):
