Parts

These parts are designed for FDM 3D printing. Parts are designed for support free 3D printing. List of parts:

• wctm-case.stl
• wctm-bottom.stl
• wctm-strap-sensor.stl
• wctm-loop-band.stl
• wctm-sensor-cover.stl

Case Assembly

The case was designed in Autodesk Fusion 360 and features sketches and editable user parameters. The design source is available to download in STEP and other file formats.

Sensor Assembly

The MCP9808 temperature sensor breakout is mounted to a flexible armband. The breakout PCB is press fitted onto built-in posts on the armband. Because the armband is printed flexible material, the posts can be forced through the mounting holes.

Flexible Parts

The sensor cover and two arm strap are designed for flexible filament. These parts must be printed in TPU material in order to function properly.

• wctm-strap-sensor.stl
• wctm-loop-band.stl
• wctm-sensor-cover.stl

PLA Parts

The bottom cover and case are designed for rigid material like PLA or PETG. These do not require any support material.

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.
