It's been a while since I posted on here but I thought this is something that might be interesting: Custom weapons! Made primarily for deluxes with 5mm slots, I received a set of weapons I made from Shapeways and I'm quite satisfied with the results.
Did you model the weapons and Shapeways printed them? I have an Up Mini and can print myself. However it's 200 micron, I guess Shapeways has a more defined 3d printer.
http://www.plasticpolygon.com I 3d design and print! Check out my instagram http://www.instagram.com/plasticpolygon3d for some Transformers weapons if you're interested. The War for Cybertron standard machine gun is ready as well as the Armada Optimus gun (smaller) and a Robotech Gunpod.
