Recently, I’ve been exploring multi-material printing. By using TPU as a connector, I’ve managed to create some mechanical structures.

I recall having planned to build a gripper mechanism for quite some time—now I finally have the chance to bring it to life.

Since not everyone owns a multi-head printer, I designed a modular version that can be assembled separately: simply print the TPU connectors and attach them afterward.

The model is easy to print using 95A TPU
