Description

A classic impossible object, the ball in a box. My amazing mother used to carve these from a solid block of wood back in the day. My first ever 3d object i used 3d tin hope it prints!
-My Mom carved these in the 70's and she got it from a book about Native American crafts i wonder if they had CC?

Instructions

I printed it on a Rep 2 at medium settings with a raft and support, 15% infill 2MM layer height and 3 shells. I seem to get layer adhesion problems randomly a couple of inches off the plate I think i might try Whpthomas's "rock-solid build plate pad up upgrade" as well as his extruder upgrade the black PLA is "SainSmart" brand from Amazon and so far about half way through the roll have had 3 or 4 dreaded "air prints", due to slight diameter irregularities (a couple mm. max) in the PLA that stop it from feeding, but when it does print it looks real nice...

I have has good luck printing these on a rep 2 using Makerware to slice, No supports or raft. 3 shells, .15 layers and 50% infill. I love Whpthomas's ear raft supports thingiverse.com/thing:38272 I add one under each span that touches the build plate and one under the ball. I gave one to my mom she liked it, yours would too...

well lets not be up on a thrown for a ball in a box like saltydoodler said his mom was making them in the 70's. just saying you dont own a tm on a ball in a box.

Cool, well my mother carved these out of wood in the 70's so she has us both! (and she learned it from a book about Native American crafts) I wonder if the indians had CC?

Holy Toledo this sucker is HUGE.  X and Y = 210000 mm and Z = 214384.9 mm

I tried to load the STL up in my favorite 3d program and it said it was an invalid format so I had to meshlab it (load it then save it) and those are dimensions this sucker is sitting at.
