I have a general question that I would like to get some feedback from MakerFarm users. I am looking to get an i3v kit and just can't figure out which size. I know it will either be the 10" or 12" but I can't make my mind up completely.

I have had (3) 3D printers up till now, each time I purchased one I new that there was nothing that I needed to make that was larger than the build dimensions, first the 100mm cube then the 150mm cube then the 200mm cube. At this point I know there is nothing that I currently wan to make that is larger than 250mm cubed, but I don't want a repeat of before wishing I had that extra 50mm. Likewise I don't want to spend on extra 10% for build volume that I will never need or on something that might be replaced in 12 months with the next latest and greatest.

So my question is in your opinion which is better too big or too small?

In case it matters I have been mostly printing prosthetic as an e-Nable volunteer and this is the main reason I am looking to upgrade my build volume (again).
