I've been using Tinkercad as my primary design software for creating objects for 3D printing for a few months now. Along the way, I've been wanting to design something different from the usual forms composed of basic shapes such as Squares and Circles from the Tinkercad Basic Shapes collection. This led me to a few videos on YouTube about creating "Organic Shapes".
As the first shot, I decided to create a simple enclosure for my Amazon Alexa/Echo Dot sitting in my living room looking quiet plain.
Back in the 80s, I had watched a movie named the "Flight of the Navigator". From bleak memories of that movie and the fact that Echo Dot is sort of an A.I. system, I decided to design an enclosure that resembled a Sentient Spacecraft.
The print time is about 15 hours for each part when printed at 50mm/sec.
This is how the enclosure would look in daylight.
And this is how it looks in at night!
Use Less Thicker Magnets
The magnets I used were what I had on hand. I'm still waiting for magnets that are less thicker than the ones I have. Also, based on how accurate the holes are, a little hot glue or super glue can help install the magnets firmly inside the holes.
Pedestal for Mounting the Enclosure
It's still in the works. However, the lower half of the enclosure has 5 holes for which a suitable pedestal could be designed.
The holes are 4 mm in diameter, and you can install 5 mm threaded Brass inserts into them so that the body of the enclosure is not worn out by metal screws.
I designed this in Tinkercad in order to challenge myself and do something different from shapes that were made up of circles, triangles and rectangles.
As the goal of the design was to stick to the "organic" theme, I selected a couple of shapes from the Tinkercad shape collection that best fit my idea:
A shape named Pineapple
Another, a Circular Trapezoid
Both these shapes are listed in the "Shape Generators" section and not the default "Basic Shapes" .
Using the Pineapple Shape to make the basic top and bottom shapes of the fuselage
Assembling the shapes and aligning them to create a spacecraft shape
Using the Circular Trapezoid to create the shape of the vents
Merging the vent structure with the spacecraft fuselage
Creating the top vent structure
Merging the top vent structure with the fuselage
Almost complete Spacecraft with the Top vents now visible on the fuselage
A suitable pedestal could be designed for the flat mounting area provided on the bottom half
Finally, adding a Simple tail fin to make the hull look more like a spacecraft

Materials Used to Print the Spacecraft
The top half was printed using eSun Natural PLA Filament (1.75 mm)
The bottom half was printed using CCTREE Glow in the Dark Green Filament (1.75 mm)
