Hi Manfred

When the new IT arrives will it have a visit to your dentist?

Regards

Kevin

Hi Kevin,
I have ordered the IT in WSF, for what no wax support material is used during printing, therefore I have to clean it only in dish detergent.

Hello everybody,
today, still a supplement to the 3D-Intertanks.

Meanwhile, Michael Key still also offers a further modified Airfix-IT. And that is the Early SLWT, which was flown since the STS-91 (ET-96), which here is presented in the new Shapeways Design.

For this he only needed to modify a few details on my previous IT,

which he thankfully has done too.

Here once again the front side with the 26 Integral Ribs and the 7 Circumferential Ribs in the Thrust Panels, etc.,

and here the back with the Graphite Composite Access Door and the Vent.

This configuration of the Early SLWTs was flown up to the STS-107 (Columbia disaster), starting with the STS-114 the PAL Ramps were omitted at the Late SLWTs, and from STS-122 then also the 7 Circumferential Ribs.

There are now three versions of the Airfix IT (1:144), my Early LWT, which is now on its way to me, and next to the Early SLWT also the Late SLWT, all of which can be found here both in WSF as well in FUD.

You do realize that both of you are making modeling history, don't you? So far there has never been such an accurate scale representation of the Intertank and its components. Great work (as usual)!

Thanks Marcell for your great compliment, which I'll pass on to Michael Key, about what he will be happy too.

BTW, from the beginning, the strange Tapering of this Airfix IT has overcomplicated the modeling process, but he mastered the problem very well.

Hello everybody,

meanwhile, I did ask my ARC friend Joe (crackerjazz) if he would not even have time and inclination for modeling the Crawler Track Shoes in 1:160, whereupon, to my surprise, he has started right away.

BTW, he did also the 3D design of the Aft Skirt Thermal Curtains (ASTCs) for my SRBs.

And what the CAD expert has delivered with the help of the drawing without further ado, is simply stunning again, I think.

There's nothing like a good technical drawing with measurements, even if they are just so on the limit of readability.

Now he has to downscale the Track shoe "only" still to 1:160, whereon I'm really curious.

Hopefully there will be some left over from the details after 3D modeling, especially as one can see based on David Maier's Paper Kit how small these things are in 1:160.

While the holes in the Pin lugs (Ø 3,3'') with Ø 0,5 mm (1:160) and the 0,4 mm (1:160) wide grooves (green) should still be printable,

the small holes (pink) with Ø 0,2 mm (1:160) should unlikely to be printable, although one should be able to live without them, because later they are hardly recognizable anyway from a normal viewing perspective.

Now I'm curious what my friend Joe is going to say, whereby Shapeways has the last word anyway.
