Question about Bounding Box Limits

Question about Bounding Box Limits [message #69483] Sat, 08 June 2013 16:01 UTC
Im trying to find this information on the site, on the materials gidelines and on the tutorials but I cant find it.

I have this model, http://www.shapeways.com/model/1143420/rikipeke02b.html very big and flat. It is inside the Bounding Box Limits. But for some reason, the moment I increase its height a little, the prize suddenly goes up extremely fast.
For example
http://www.shapeways.com/model/1143416/rikipeke02.html

Both models are the same, the only difference is one little stick and suddenly the price is over 70â‚¬ more. Why does this happen? Is there a Bounding Box Limit that increases the price?

Maybe it's down to this:

 Quote: We also offer a volume and density discount on Strong & Flexible materials. For models that are greater than 10% dense (material volume divided by bounding box volume), after the first 20cm3, the remaining volume is calculated with a 50% discount.

What are the actual prices of your 2 models?
Which material?

Also go to the Model in Edit Mode and check out the Oriented Bounding Box data - this is what is used in the calcs.

The first model costs
101,06 â‚¬ (132\$) in white strong flexible

Oriented Bounds (used for determining printability)
In: Â  13.6 w x 6.5 d x 0.4 h
Cm: Â  34.5 w x 16.4 d x 1.1 h
Vol: 133.02 cmÂ³

The second model costs
174,7 â‚¬ (227\$) in white strong flexible

Oriented Bounds (used for determining printability)
In: Â  13.6 w x 6.5 d x 1.4 h
Cm: Â  34.5 w x 16.4 d x 3.5 h
Vol: 133.06 cmÂ³

The spike makes your models print density lower than 10% therefore you don't get the discount.

Indeed.
Thanks.
