Description

A model of the SpaceX Dragon spacecraft V1. The model depicts the variant that is used for NASA's Commercial Resupply Services program. This model is drawn in inches to true size, this was done to make it easier to change and keep track of its scale.
Certain aspects of the model were drawn inaccurate on purpose because to draw them realistically would cause problems during printing (Ex:solar array thickness, trunk thickness, trunk depth, alignment guides on the Common Berthing Mechanism...).
I created this model because I wanted something more accurate than the model already on Thingverse.

Note: If you use this model then remember the license requires you to attribute. Do not be like University of Illinois' Immortal team and try to pass it off as your own work.

Please let me know if there are any issues with the models.

**Model description:** Capsule, trunk and solar arrays are one piece. Capsule has no detail.

**Model description:** Capsule, trunk and solar arrays are one piece. Capsule is heavily detailed.
- Dragon spacecraft joined“ complex.stl
**Model description:** Model is meant to be displayed on a flat surface and is intended to be assembled without glue. The trunk is removable and the solar arrays can be rotated a full 360 degrees. The capsule is heavily detailed and has four holes on the bottom of it to help keep it attached to the trunk. Trunk depth is limited to avoid conflicting with how the solar arrays are attached. This is the version seen in the main image.

I just posted a modified trunk. It is a work in progress but currently has an enhanced cargo hold. I'll work on exterior details next.
The exterior trunk diameter is actually 144 inches, 142 inches is the interior diameter. Right now I'm working on rescaling certain parts of the model for accuracy.
I've modified this design so it can be printed by Shapeways. The model is available here: shpws.me/ojnC
I've also created other parts needed to build the SpaceX Falcon 9 in 1:144 scale.

When I open the file dragon_capsule_complex in my CAD app, the diameter is given as 138.85". That looks a bit underscale to me.

From the Dragonlab datasheet, the trunk diameter is 3.6m/142". From photos, the base of the capsule should be 1.0666 times larger than that, or 3.84 m/151.2".

To correct for this, the drawing must be scaled by a factor of 1.0888.

manboy, do an Orion MPCV next!
I try not to do spacecraft that haven't flow yet because the more complex models take a lot of time and the design may change prior to flight.
Looks like someone on flickr printed it

excellent detail! any chance you could post the source file? i'm interested in designing an entire Falcon 9 for use as a beer tap pull for my kegerator. i'll have to tweak the design a bit to make it usable for that application.
"any chance you could post the source file?"

Done!
Great capsule. I have been wanting a Dragon for some time. How did you make it so detailed?
I printed in roughly 1:48 scale. First I sliced it into 3 pieces so I could print all with out supports or rafts. Sliced off heat shield just below main hatch, as indicated by photos of Dragon in orbit. Also sliced off the top with the docking ring just where the main side wall steps. Printed central section in white with 0% infill. Printed top in white with 20% infill. Flipped heat shield and printed flat side down in gray with 20% infill. All with 4 shells and 0.075mm layer height. Came out beautiful.
Any chance you could do the trunk with the same level of detail?
BTW, you cam make he solar panels much thinner, like 2mm, and it prints fine standing on the long edge.
"How did you make it so detailed?"
Lots and lots of work. I used the DragonLab dimensions posted on SpaceX's website as a base template and than modified it based on a lot of pre/during/post-flight pictures from the SpX COTS demo 2 mission.

"Any chance you could do the trunk with the same level of detail?"

I currently have no plans to make the trunk more detailed but I don't have any problem with someone else modifying the files and doing it themself.

There are no files associated with this thing. :(
 I was trying to fix the thumbnail, the file is backup.
