Modular Baby Gym – Printable Hanging Toy Frame

Modular 3D‑printed baby gym designed for standard 20 mm wooden rods

This model creates a stable hanging frame for toys, rattles, and sensory objects. 

How the system works 

The legs and the top bar use a friction‑fit wedge mechanism. The wooden rods slide into the printed connectors and lock in place by friction. The joints hold firmly but can still be adjusted with controlled force. No screws, no drilling — a true print‑and‑play design.

Fits common 20 mm wooden rods. Measure and cut yourself, mine worked with 1.2 m bar and four 0.5 m legs. But I'd recommend making the legs longer and adjust length as desired. 

Printed with Filamentum ExtraFill PLA with 0.28 mm layer height, 5 % infill and supports enabled. 

Works just fine, but feel free to explore more print profiles. 

I hope you'll find it usefull. 

Safety Notes 

– Always use under adult supervision
