MY COMMENTS

So in anticipation of getting the "Basic Electronics Kit" - http://www.ponoko.com/showroom/MakerBot/cupcake-cnc-basic-electronics-kit-4242
from Makerbot, I whipped up a Birch plywood body to see how it would work. The original files in the Makerbot showroom have the tabs and holes drawn for 5mm material. The Ponoko Birch measures 5.3mm so I figured that with laser kerf the holes would come out at about 5.2mm. I guessed that would be close enough to get body together. Well, that 0.1mm difference was enough to be difficult. Having worked with plywood for many years I knew I could use a rubber mallet to nudge the pieces to together without anything breaking. If I were using the bamboo this would not have been possible as it is not a ply construction and therefore can break along the grain, especially where a short grain situation created. There were some cosmetic issues because of the tight joints which I have shown in the 3rd photo. some of the veneer around the holes broke out but it is nothing that will affect the structural performance of the machine.

So anyway, I have adjusted the files so that the holes for the tabs are drawn at 5.3mm. This should work better with the Birch and Bamboo in the Ponoko catalog. There may be other areas where the 0.3mm difference in material thickness multiplies to cause tight parts. For instance, the panel that covers the power supply seemed tight but I can't make adjustments there until I get a power supply and the other hardware to know how that part goes together. And of course thickness variations in the material can make things difficult at any time.
