Fully Modeled In Inventor, its pretty close to 1:1, im currently in the progress of printing this behemoth ! Will update this posting when its done, All the parts that should be printed are included in this file. I will be using 4 2-foot 2"diameter pvc pipe sections for the rocket tubes, metal conduit pipe (about 0.7 inch outer diameter) for internal connectors and one of the pipe details, aswell as a short section of 3/4" pvc for the forward grip.
I also included in the same file, a full version of the launcher unsplit if you want to print one smaller than 1:1
Tolerances are wonky, so sanding will most likely be necessary for proper fitting/assembly.
If you print one of these guys, post a make ! I want to see it !
