Description

n-Sphere Tiles
Designed as an educational toy for my son, the n-Sphere toy is a little puzzle box with no wrong answers. The sphere can be assembled any combination of 6 tiles oriented in any rotation and will always yield a continuous topology of ridges and grooves along the outer surface.
This version is designed with a flat base surface so no support needed with the makerbot.

Version 2 updated for Medium Resolution prints at:

I was printing straight on the bed with a pretty decent success rate. However for the mini and micro versions I was printing a raft, but no support which gave me very insistent results. A quick pass with the exacto around the edge and the piece was good to go.
I had trouble printing this on my rep2 with wingcommander's 100m profile. The little triangle pieces inevitably disconnected from the painter's tape on my build plate within the first few layers. Any advice?
Shapeways version of the model has been redesigned to reduce overall material area and therefor cost.
Also added 2 new sizes,

Two new sizes can be replicated with the Thingiverse version of the model by scaling the medium resolution version down (0.75, Mini), (0.5, Micro)

I made the initial model on the high res setting on a replicator 2, I'll post an alternate version in the next few days with a larger gap at the connection and test the tolerances on a medium resolution print.
Models have just been updated and properly scaled to mm.
Awesome, suspect that was what happened - printing as I type! :-) Overhang on the tags is going to be interesting!
Excellent model, but I think the scaling is off? Each piece is about 2.2mm, so maybe modeled and exported in inches?

Thanks for catching that! Revising the model now, will post an update today.
this is nice, specially since you can put it together in any way and get nice shapes, took some time to design?
