Description

For those familiar to the injection molding world, you know such a design would be very difficult to produce or assemble. When printed, the ball remains captive inside the cage. You'll probably get an eyebrow if you show this to an engineer in the industrial world.

Is the ball hollow ?

=O

That's awesome.

Thanks, much better. I appreciate the design. I have been wanting to try an outrageous overhang-bridge thing.The bottom of the ball and a little of the inside of the top sagged but it worked better than I expected. I forgot to reduce my fill density causing all the little bumps on the columns.

I haven't printed this. I ordered my makerbot recently and was trying to come up with some parts to test my system once it's built. So feel free to let me know how this one goes.

How about changing the license on this item. I think the all rights reserved license removes the I made one button on this page.I would like to upload my print out of this thing :)

No problem. Does it work now?

Okay I made one at 1.5 time the size here in order to take advantage of the increased resolution. Unfortunately I printed it too dense and after 2.5 hours the extruder failed. The good news is the ball is completely closed in. If it had finished I'd say there would be a lot of plastic lost at the center near the end. Really neat regardless!

Cant see the top w/o downloading this, but...if the hole at the top is fully open, its fine. But where the top joins the side should be a 45 degree angle.

Also, the bottom of the sphere probably won't build well. But an icosahedron with the flat side down would print fine...but maybe not look as cool. I still think this could be fixed with better algorithms in skeinforge. I need to experiment with gcode to test.

As it stands, your overhangs at the top of the box aren't makerbot printable due to overhangs. You can easily fix this by covering the hole at top to create a "bridge" such that the surface plastic attaches to both sides. This actually works very well because ABS shrinks as it cools. Difficult to make any more recommendations until I try to print it. Welcome to party!
