Here is a pic of the airplane ones I printed out. I didn't design these cutters (only the NSX one). Someone posted the design for these on thingiverse so I downloaded them and printed them out. These got me thinking as to what else I could make into a cookie cutter.
I purchased the Makerbot Thing-o-matic last year. Wish I would have waited. Now there is the Ultimaker and the fully assembled Replicator. That is how it always is though. You buy something cool and then they come out with bigger and better versions. Sigh. Drop me a PM once you get it running.
