Temperature Sensitive Snowflake

Since snowflakes are often seen as a pictograph for temperature so too is this one! Full R->G->B sweep from 15C-35C (60F-95F) and haptic mode control.

While its rotation and loop based rendering are certainly a standout feature I also I wanted to see how BlocksCAD went at building something functional that also included non-symmetric components. Was impressed with its ease of use and understanding.

Everything friction fits together. The board should snap onto the mounting lugs and the diffuser requires a little pressure to seat it into the base.

Excuse the under extrusion on my diffuser ;) Support is only required for the internal battery compartment, easy to remove.

Inside is a battery or USB powered Adafruit Circuit Playground (code enclosed). There are many styles and sizes of lithium ion batter
