Title: 1/350 Spaceship designs
Post by: Frank3k on December 11, 2020, 01:47:49 PM
These are a couple of renders for small (115mm/ 3.5" tall) 1/350 spaceships that I just finished drawing and will print soon. Actually, 4.5" isn't that small, print-wise.

The first is a late 21st or early 22nd century Mars or Titan lander, inspired by the artwork in this Hackaday article: (https://hackaday.com/2020/09/14/floating-spaceports-for-future-rockets/)

The landing gear struts are not part of the finished model and are just representative; I'll have to find something that works.

The second one is of a 21st century Pluto/Kuiper belt explorer. I actually dreamt of something like this... The round blobs on the side are observation domes for the crew:

This is a view of the docking/sensor/cargo bay area at the top. The smaller airlocks are about the height of a human:

The engine section. The main, central engine uses advanced Handwavium Physics for propulsion, and it can get to 500AU in about a month. The engine should be familiar to anyone with a Leif Ericson kit. I just used it as an inspiration for this design (and "borrowed" some of the details from the 3D files I used to make the kit engines for Round2):

I should have these printing by next week.

Becoming quite the dab hand at this 3D stuff.. well done Frank

Fantastic Frank, I look forward to seeing some plastic printed!  8)

Thanks guys. The Pluto explorer alone will take about 14-15 hours to print (in three sessions). They are big.

 Really nice combinations of the classical "Space Age" imagery and the genuine hardware. I really like the faired landing leg pods, and yeah, the Leif 'Advanced Ion Engine' is the stuff.  Can't wait to see what you do with the finish.

Cool designs Frank, how many man hours did it take to produce them ?

For both, about 4 hrs each in Rhino3D, which includes going back and redoing parts.

@Dr Yo - I knew you'd recognize the engine!

Hey, pretty good it would take me weeks to achieve something like that !

I have the Pluto/Kuiper belt explorer printed (mostly).

The first print is missing the middle ring:

I ran out of ABS-like resin, so I continued printing in Siraya Build, which is a strong, tappable resin. It's also smokey clear:

The middle ring is re-printing right now. This copy has issues, so I taped it in place. The dust is sanding dust. The legs are round styrene tubes - the landing pads and other bits are printed, but they're small and delicate.

I designed both ships in sections, for easier painting and also to get better with 3D printing tolerances. Since the parts are designed to friction fit into each other, I added the gray upper section for a stretched or cargo explorer:

To get a sense of scale, here's a closeup of the two 1/350 scale astronauts at the top, from a long stalled build:

Here are Leif-like engines:

The metallic sheen is pretty cool. I may just leave the engine mostly clear and light it internally.

Back to the original design goal - getting to 500AU in a month would be too close to fantasy... let's make it 10A AU/month. Don't want to make the trip a vacation.

The Mars lander also had one section print poorly, so I'm reprinting it as well.
