About the model
A true fairground classic for your layout
Wellenflug brings the elegant motion of a classic swing carousel to an H0 fairground as a fully functional 3D-printable model. While the main platform rotates smoothly, it tilts gently to create the characteristic wave motion. The freely suspended seats swing outwards as the carousel turns.
Features of the H0 model
- rotating and tilting carousel platform
- 32 freely swinging seats
- two 6 V N20 geared motors rated at 30 and 60 RPM
- SG90 servo for precise tilt control
- Arduino control with an L298N motor driver
- motors integrated into the design for a clean appearance
- two variants for the outer roof trim
Printing and assembly
The parts can be printed in PLA or ABS. Assembly starts with the base plate, the two drives and the tilting mechanism, followed by the tower, roof and seats. Additional 0.6 mm copper wire is required for wiring.
The illustrated PDF guide contains a complete parts list and 21 assembly steps. The matching Arduino control code is available on GitHub.
