Correct sized Module

This is the first of my own designs to complement the outstanding work done by Primitive Dave on this subject unfortunately some of his files which he generously lets folks download was corrupted and I am trying to fill in the gaps best as I can, all these will be scaled for approximately 1/700. UPDATE: select module final if you wish for a corrected more structurally sound version. UPDATE added the control center and rcs thrusters for bottom of the Modules VERY IMPORTANT: Do not attempt to print this first....I have to finish the original designs of the bow and stern modules to get a better fit for this, when I do I will update the file and flag it as complete and good.FINAL UPDATE: I was able to crack the code on the remaining Perfect Dave modules this will match up perfectly(hence the name) with the BOW and Stern fuel Modules UPDATE FINAL! new module uploaded use this one for best results and appearance in comparison to other modules
