Add the upgrade.. badBrick Upgrade kit for MakerBot 5-Cylinder Radial Engine Instructions for the upgrade kit. Print (1): Twist_Prop.stl Layer Height: .20 Print (1): CrankCaseBracketSet.stl Layer Height: .14 cylinders. I super glued mine, so they stay.. Print (1): ExhaustPipeMountsSet.stl Print (1): ExhaustPipesSet.stl Print (1): ExhaustPipeBracketSet Layer Height: .14 Lightly sand these parts but leave them a little rough for more of a snug fit for positioning. Press the Exhaust Mounts on to the Curved end of the Exhaust Pipes. The Exhaust mounts also have pseudo mount holes that line up with the tiny mount holes in the CYLINDER HEAD. So you can use those as guidance postioning. You can also reference the attached pictures. These parts are snug enough to just sit undisturbed on their own. However this model is a magnet of interest for anyone you'd like to talk to. I have 3 kids (boys..) Sooo... I suggest getting them positioned as you want them and then dropping some super glue to permanently set them. I also super glued the cylinders down too.. Made for a much more "play-with'able" model. Print (1): HandHolder.stl Layer Height: .18 BTW.. Thank You MakerBot for your 5-Cylinder Radial Engine Model and all the files you posted. They are a gift for learning. In the same vain. I have included all .skp files as a free for all. I hope this little engine will crowdsource some wings :-) Ren [badBrick]
