3D Printing

3D Printed Bumper

This is a simple 3d printed bumper for the Adafruit NeoTrellis M4 designed for flexible filaments. This provides protection and comfort to the acrylic case.

Flexible Filaments

The bumper features a cut out on the back side for cables. The design is optimized for 3D printing using flexible filaments, such as Cheetah Ninjaflex and does not require any support material. 

How to 3D Print Flexible Filament 

Our learn guide will walk you through some common practices for 3D printing with flexible filaments successfully.
