[TriLUG] can someone to do a 3D print job?

Hi Joe,

I just replied to the list with a link to my 3D Hubs site.  I'm also 
taking a look at the model you want to print.

Seems that if you just upload it to my hub for a quote, you get a 
ridiculously high quote, because 3D Hubs bases quotes solely on volume, 
which of course scales along a cubic function.  I would not charge you 
$140 to print your items.

It looks like each side of the globe requires about 175 g of material. 
At a dime a gram, that's $17.50 in material per hemisphere.  Each print 
would take about 10 hours to run, so a total of $30 per hemisphere seems 
appropriate for such a worthy cause.

Ergo, despite the high price displayed by 3D Hubs when you request a 
qoute, I'll run your job for $67.50, which includes $7.50 in postage to 
ship the final product to you.

About your model in particular: It looks like there are a lot of very 
pointy features in the low-elevation areas which simply won't resolve 
well with FDM printing.  I'd be inclined to run a smoothing algorithm on 
the geometry to improve overall results.

Let me know if that sounds reasonable to you.

Cheers,
-Brian
