Agree that you should be charging for the printing skill, but not for babysitting.
I charge depending on the complexity of the project and how much of my printing skill it uses, but then allow for the fact that I am doing something else while it is printing.
I also allow for a return on investment charge for the printing, and the hours I have put in to managing to print at all!
So there is a fairly high set up of about UKP25 and then I work out how many hours to handle the part and clean up and then packaging and delivery - I rarely think too hard about the plastic volume as I think that is a fairly small element in the whole process.
I am never cheaper than the local hub, but almost always cheaper than shapeways unless it is a really small item.

so i charge 4 euro setup costs and 0,21 euro per cm3.. and that makes me an acceptable amount of money![:)](//content.invisioncic.com/ultimake/emoticons/5a33abdf6d109_1f60acopy.png)
how large would you consider a large piece?
i think you might need to tweak your setup a bit if it needs babysitting.. i do 40 hour prints on a regular basis and i just let it go.. my failure rate is around 1 percent..
reel tangles to me means you need to buy better filament![;)](//content.invisioncic.com/ultimake/emoticons/5a33abe00be82_1f609copy.png)
