Snap Fit Case

This case is designed to protect the Adafruit MagTag. It features cutouts for the four user buttons, USB-C, and on/off switch. The reset and DFU side buttons feature reliefs that allow the overlays to actuate the switches. 

You may also use vinyl to create covers with beautifully glossy holographic decals.

Desktop Stand

Want to prop up the MagTag on your desk? This simple 3D printed stand mounts the MagTag at a 70 degree angle for perfect viewing. The wide bottom prevents the stand from tipping over. An hole in the lower center allows a STEMMA cable to pass through for connecting other I2C sensors.

Case Assembly

Install Front Cover

Line up the four user buttons with the cutouts on the front cover. Place the PCB into the front cover and press so the pegs are fitted into the standoffs on the MagTag. Reference the photo for correct placement.

Install the battery and use double-sided scotch tape to stick the battery to the back of the MagTag. Right behind the silk screen graphics of the refrigerator is a good spot.

Install Frame

Orient the frame with the cover by lining up the side buttons with the opening on the frame. Insert the frame into the front cover and fit the edges into the snaps on the front cover. Press to snap fit together.

Secure Back Cover

Use 4x M3 thumb screws with magnets to secure the back cover to the frame. Place the back cover over the frame and line up the mounting holes. Insert and fasten the four screws.

Final Case Build

And there you have it! The case is ready to use. You can adorn the front cover with vinyl.

Stand Assembly

Screws for Stand

Use 4x M3 thumb screws with magnets to secure the MagTag PCB to the 3D printed stand. Place the MagTag over the stand and line up the mounting holes with the standoffs. Insert and fasten the M3 screws to secure the MagTag PCB to the stand.

Installed Battery (Optional)

You can use the 420mAh Lipo battery with the stand but it's not necessary. Use a USB-C type cable to power the MagTag or use the Lipo battery. 

Final Stand Build

And there you have it! The MagTag is setup on a stand and ready for use.
