This simple case protects your Garmin DriveSmart 61 GPS while you're traveling. I was always afraid that it would be damaged in my luggage, so I made this to keep it safe. Just print it out, place the GPS inside face-first, and secure it with a rubber band... then it won't get the touchscreen damaged in transit.
The i3 Mk3 prints very dimensionally accurate, and this is a close fitting (0.010" all around) case. If your printer is a little less accurate with its prints, consider scaling it up a tiny amount (0.5-1%) to make sure it will fit.
