16x16 LED Matrix Diffuser Enclosure for Stencils
Adafruit Blog
EDITOR BRIEF
This is a 16x16 LED matrix enclosure made to work with stencil sheets, and it follows the designer’s earlier 8x32 version. A March 2026 update re-uploaded missing STL files and added vented parts to help with heat when running at full brightness. The design also includes ridges and notches intended for alignment, and a YouTube walkthrough is available.
INSIGHTS
For learners, this is a good example of designing 3D-printed parts around an electronics project. If you are building an LED display, try thinking about heat flow, file organization, and how small shape details can make assembly easier.
