Any chance you're going to make the egg cup with the bird available?

Thanks,

Yes I should have mentioned I'm yet without a printer, so this one was made on an SLS printer in nylon.

I'm curious though how this will turn out on a home printer. It will need some support I guess.

Printed - check out the pic. It's a nice design. The dips in the hearts I knew wouldn't print so the hearts look a little like flattened lacey loops. I did no cleanup on this and it came out better than I expected it too.

If the design were tweaked a little bit to account for the layer thickness the printer was capable of and adjusting for "impossible" overhangs. Full support may have helped create the dips but it likely would have torn apart removing the support since it's so delicate.

Looks nice either way!

Nice!

Looks not too bad at all :)
What do you mean by adjusting for layer height?
How's the strength and flexibility?

So the layers that the printer can build depend on the model. Stock 0.3 mm is a good thickness..is very subtle curves - like the one on the base have slightly jagged transitions.

There are a couple places where the wall thickness is in between what the printer is capable of (like where the base meets the "cup"..making this a larger multiple of the print resolution would ensure it could be filled solid where desired...in fact a lot of the lower part of the cup is so thin it
's only a single wall of plastic - which isn't very strong.

The sides printed better than I expected them too with only the dip in the hearts getting clearly falling off. These would be very difficult overhangs to print even with support since they are so small.

The very top heart lace - because
of the way Skienforge sliced it ended up being made of little stacks of circles. It's got a little flex but anything over an 1/8" or so and it might just break. Making the sides a little thicker all around would do the trick.

On the base - instead of having it hollowed out (I know shapeways charg
es by the cubic cm) I would make it solid and print with a 30% infill In order to print it I had to use a raft and support material under it as that shallow curve would be impossible to print otherwise.

It's really a nice looking piece. I may try printing in a different color as this is the last
of the natural that came with my makerbot and I have had issues printing with it.

Knowing what wouldn't print I was still pretty impressed with what came out.

Thanks for the detailed explanation,

I've now uploaded a new version with 2mm wall thickness and a solid base

Thing-O-Matic w/ MK7

I'll give it a try...I might need to make the base solid - but I'll give it a go as is.

Looks great what did you print that on?
