Thanks for the video. What a great result with all the attention to lighting as well as the intricate detail. Scary to approach such a large complex spaceship without the superglue in hand. Incredible build. Time to play the movie again.

Sorry if this has been asked already, but is there somewhere with all the files for 3d printing this beauty? I have all the Primitive Dave ones, but quite a few of them were busted and the files cant be opened..

would it be possible to list them all if you haven't already?

Cheers

Hi, This is the list of parts that was originally on Primitive Dave shop back when I was getting them printed. That was maybe 5-6 years ago. I have not checked it against what is up there now.

Also there are some parts on Thingiverse that are based on Primitive Dave's (I think) but may have been modified by the poster.

Hope this helps and good luck!

Probably too many pictures for this update but here goes. The connection between the bow and the center armature parts is a major pain in the ass. I guess the design was not really finished or it could be that I am just not looking at it correctly. Either way I just could not get the parts to fit properly with the original design so some improvisation was needed. The armature part between the two areas need to be significantly slimmer so thankfully my son's skills in Solidworks saved the day. He redesigned the parts and I had them recut. That was a whole other drama with Pololu and file formats but I have to say their customer support was unbelievably amazing. The large hole in the piece was designed in for running wires. Now the armature insert sits flush with the 3D printed model part which it was not doing previously.

While I was waiting for parts to be cut I continued to detail out the center span. There are tanks that fit into either end and they are a bit of a puzzle. I figured it out eventually from looking at reference pics but it was a head scratcher.

Very impressive SZArchie.

You mentioned SolidWorks above. Did you and your so design the whole thing in SolidWorks outside of the exoskeleton?

Speaking of the exoskeleton were those previously designed by someone else.

I'm a complete novice so thanks for your patience.

Marc.

Hi Marc

Welcome! Glad you enjoyed the USS Cygnus build. We did not design the model. That was done by a guy called Dave "Primitive Dave" Nelson. There is another, much longer Cygnus thread here on the RPF that goes into that. He took the model about 99% of the way but there is a problem with the Bow armature connecting to the center span armature that needed to be fixed. That was what my son was using SolidWorks for to try to get that last 1% sorted out.
Dave has a shop on Shapeways that sells most of the parts I think and another guy Kremmin (I think) sells some of the missing ones. Its been about 5 years since I bought my parts so I am not entirely sure what is there anymore.

Best

John,

Thanks for your kind reply. I replied earlier but for some reason it wasn't posted - doubtless my own fault.

Was there anything except the bow armature connection to the centre span armature that your son designed in SolidWorks that you needed to design yourself?

If available I'd love a copy of the SW files you made.

I've seen the other thread also and got some great input there from Jeff.

Best regards,

Marc.

Hi Marc

We did design some spacers as well and I think we used one, maybe two as sort of shims to get a better fit. I'm attaching pdfs of the designs and the materials we got them made in. I cannot attach the SolidWorks files as the format is not allowed on the forum for what ever reason. BTW we used a company called Pololu to get the parts made.
