Mini Train - Functional Future City Diorama
This is the sixth Mini Train Diorama and this is my approach for a future city design. Green meadows without streets or cars and clean big buildings with a lot of space. In the heart of the city is the newest technology, the particle accelerator power plant that generates clean electricity while spinning.
The design includes a mono rail train and large curved buildings which are integrated into the track.
In the GIF you see the additional motor box in action but as in the other dioramas, you can turn the hand-wheel on the outside to let the little train drive.
The power plant is moving, as well. And you have 2 options. Attractive and repulsive magnets:
- It's pulled downwards by a helix and repelled by the magnets, making it spin really fast.
- If you insert the magnets the opposite direction the power plant slides up and down, looks like a pounding heart.❤
→ Decide what you like
The new Future Track & Train is 100% compatible to the previous designs.
All printed parts are designed to get an good result with a 0,4 nozzle and this time i tried to use less colors and reduced color changes for a fast printing time.
More is coming… stay tuned….check the “Mini Train collection” and leave a follow👍
Printing:
Note that some parts are very small. Good adhesion is necessary!
Following PLA Basic Filaments are used
White
Turquoise
Bambu Green
Brown
Black
Silver (just for the track →brown,cyan or black works also)
Other colors are possible of course, look what you have in stock.
I think it could be easy done with single color, if you want to color from hand.
I printed with a 0,4mm nozzle! Iam very pleased with the result but you can try a 0,2 nozzle as well.
Assembly:
*watch this video from previous design:
You need 6pcs round 4x2 magnets magnets for the train and 8pcs 4x2 magnets for the power plant.
- Insert 3pcs Magnets in the train and wagon with same polarity
- Insert Magnets in the 3 pins all with same polarity but opposite direction than before! The Pins must attract the train
- Insert 4 magnets into the hand-wheel same polarity and same direction like the pins
- Now two option:
- Fast Spinning power plant: → Insert 4 magnets same polarity and same direction like the pins
- Pumping power plant: → Insert 4 magnets same polarity and same direction like the train
- Terrain on top and press trees in the holes. You can add a bit of glue to combine.
- Place the power plant in the middle
- Place the train to the magnetic position and have fun 😀👍
I hope you like this little project.
