Summary

this is a remodel of an earlier design.
I had a few people that wanted a new version with rounder engines.
so that's what this is

no supports are needed
printed ok at ~= 70 mm (as pictured)

spacepudge2XL.stl is a thicker engine/tip model for sturdier print.

Instructions

no supports are needed
printed ok at ~= 70 mm (as pictured)

In response to user having issues with the tips of the engines breaking off
I have made a version spacepudge2XL.
this has thicker engines and tip of the rocket
to allow stronger print in smaller size.
I have attached a picture of the new model in 2 small sizes.
the really small one is not a good print and is there for
the sake of demonstrating a too small print.
at 2 1/4 inch tall (55 mm) it has much stronger tips that wont just break away. I used 2 shells 0%infill.
I suggest in addition to make the models stronger try the following.
(I am assuming ABS is used)
i use the new firmware and it has a hotter nozzel temp (240 celcius)
this seems to make the layers bind together better.
a post print paint with acetone helps to bind the layers as well.
