Mikey, good question, but the cost of trucks does not apply to desktop printers at this time, cause with most home printers, one cannot get the resolution needed for an HO scale truck. For that, search railroad trucks at shapeways.com. That will give you the answer on 3d printed trucks from shapeways. The lowest price desk top printer I am aware of that will do a truck in HO scale, would be the FormLabs1 printer, and sells for $3200, and the material it uses, an light cured acrylic polymer, sells for $149/liter. At this point, I just can't justify the cost versus benefit. I wish I could! 
As for pricing on the above shop/machinery shed, I would sell it for $28.00 for the 3d printed parts. Just the 3d printed parts! That covers a guess at the amortized cost of the printer, plus the material cost. I have a few items listed for sale at <!-- m --><a class="postlink" href="http://hurleysmrs.blogspot.com/">http://hurleysmrs.blogspot.com/</a><!-- m -->, and I have a shapeways shop for some small detail items, <!-- m --><a class="postlink" href="http://www.shapeways.com/shops/nvrr49">http://www.shapeways.com/shops/nvrr49</a><!-- m -->.
