Update 01/11/2025: added profiles for Bike Handlebars. 

The Stroller Multi-Toy System now includes a brand-new attachment:
a bike-style handlebar module with ergonomic grips and an optional horizontal smartphone holder.

This accessory is designed with safety in mind: unlike a free-spinning wheel, the handlebar rotates only 45° left or right. This prevents excessive twisting that could cause discomfort or injury while still providing a realistic steering experience.

When the phone support is installed, the module amusingly resembles a submarine periscope, adding a playful imaginary dimension during walks.

Just like the other toys in the system, the handlebar connects instantly to the existing mounting interface — no need to detach the main stroller clamp. More modules mean more fun… and more opportunities for creative expansion.

Update 31/10/2025: added profiles for each toy and main support. 

Stroller Multi-Toy System

The Stroller Multi-Toy System is a modular, 3D-printed entertainment solution designed to mount directly onto the front safety bar of most baby strollers. Once the main clamp is installed, toys can be quickly swapped without removing the support from the stroller, making it practical for both indoor and outdoor use.

The system uses a robust clamping mechanism with adjustable screws to ensure a firm and secure fit on bars of different diameters. The interchangeable toy modules connect to the main support through a standardized interface, enabling fast attachment and removal while maintaining stability during movement.

Included examples feature:

• A playful Tesla-style steering wheel, fully functional and perfect for imaginative driving sessions.
• A lever control panel module with multiple colored levers that encourage fine-motor skill development.

This platform is designed with expandability in mind. Makers can easily design and print new attachments—buttons, fidget modules, educational elements, themed accessories—opening the door to a growing ecosystem of stroller-mounted toys. Only the accessory changes; the support stays installed.

Whether you want to keep your child engaged on the go or experiment with new 3D-printed ideas, the Stroller Multi-Toy System offers a practical, customizable, and future-proof solution.

Key Features

• Modular and interchangeable toy attachments
• Secure adjustable clamp for stroller safety bars
• Child-friendly ergonomics
• Fast swap-in/out mechanism
• Expandable for future accessory designs

Perfect for makers, parents, and anyone who enjoys modular, printable creativity on wheels. Enjoy the ride!

NOTE after printing the Steering Wheel:

Because the steering wheel is printed in place the rotation is not functional until you will brake the internal connections. You can easily do it by a tools or using a vice as help.
