UHU02 says the skin is designed to make it removable. I really don't think this is a logical choice. If you realize all the internal details you won't cover them to hide all the work you've done with great efforts. And if you put on the skin it will be left there, it's not easy to dress this baby and the structure can easily suffer for all the manipulation needed to put the covers on. I didn't even try to cut away the external skin from printed pages to do some "dressing tests" so I really don't have a direct experience about it but my advice, for anyone who wants to try this build, is to choose - before starting the work - the "naked" or the "dressed" version.
Otherwise you can thake an half-way choice and realize a cut-off like the wonderful realization by mk310149... For my LEM I preferred to leave all the work visible, I only took some of the details UHU left for the last phase (thruster deflectors, EVA antenna and docking reference that were intended to be fixed to the outer skin) and pasted them to the "naked" structure. |

Part 264 is an octagonal guard pipe at the bottom of the descent stage. It is formed by folding in half for 2-sided printing.
Parts 265 through 268 are the outside panels of the quads and include some of the landing gear struts. The lower struts are folded in half for 2-sided printing. Each of the 4 panels are a bit different so be careful about mounting them in the correct quadrant. Part 269 is piping connected to the 4 large descent stage fuel tanks. It is folded in half for 2-sided printing. Part 270 is the top panel of the descent stage. It has some interesting folds to form some 2-sided printing. Now for installation of these parts. First was mounting the 4 parts numbered 254 which are protective shields mounted below the tanks. Next I mounted the 2 parts numbered 255 which are mounting brackets for part 269. Next I attached parts 265 through 268 on each of the quadrants. The last part I installed was 270 to close in the tanks. Part count to date: 544 |

I would suggest to cut away some of the grey areas from the struts and pipes (where possible).
It involves a lot of blade-work (and several dioptres lost) but it's worth the effort, in my opinion. The resulting pieces are somewhat weaker, but with some extra attention (especially at the end of the work when you will move the model from one expo to the other...) you can avoid any damage. A different question are the grey areas in leg struts junctions (see, in photo #1, leg parts in background. I even tried to darken the grey areas but didn't like very much the result). These spots are zones where many forces converge and grey areas was added to strenghten the general structure. Cutting them away could lead to a catastrophic collapse of the entire landing gear under LM own weight. I was very doubtful whether cut those areas away or not. I finally choose to reduce grey areas considerably (see photo #3 and 4) and, after build, I reinforced all the struts, especially in the junction points, with a mixture of white glue and water (invisible once dried, see last photo). Eventually the legs held the weight very well and now, after more than a year of standing, no trace of failure seems to appear (so far...). Consider that I built the model in his original scale, perhaps my findings doesn't apply to an enlarged build... |

Tonino: Excellent suggestion on cutting away some of the gray areas on the octogonal guard pipe and leg struts and junctions. I removed the guard pipe (part 264), removed the blacked out areas, and reattached. It looks much better. Since the piping connected to the 4 large fuel tanks (part 269) would be a dit difficult to remove and will be covered later in the build, I felt it would be best to leave in place. For the leg struts and junctions, I trimmed away the gray areas. Will see how much reinforcement may be needed later in the build. May use superglue to plasticize, but want to make sure their positioning it finalized before doing so.
Thanks for passing along the great ideas! Keep them coming. |

My build
Great work! I have built the same model. I scaled it up to 1:28. It was digitily printed on 12pt card stock. I took me about 8 months to build. Here are some pictures.

Part 271 is the front mounting bracket that attaches the Ascent Module to the Descent Module. There are a couple of folds to give it 2-sided printing. Pretty straight forward. It was then attached to the Descent Module.
Parts 272a/b form the S-Band Antenna and mounting strap. It is a basic tube with end caps. On the part sheet the end caps are attached, but I separated them because I find it easier to form the tube with them detached. Part 273 is a battery assembly. Both were mounted in Quad 1 (front left). I used the opportunity to make sure the Ascent Module and Descent Module attachment points were aligned. A few minor tweaks to nudge them into place. I took a few extra pictures to show the positioning of the attachment points, and to show the current progress of the build with the Ascent Module attached to the Descent Module. Part count to date: 548 |

Stunning job! It looks appropriately spindly....

Your LM is looking fantastic, but the model is certainly a very fragile object and accordingly to handle with care, right?
