BT-NaviButtons
thingiverse
Nice little gadget for enhanced control of my navigation app on the Android smartphone. Zoom and pan the maps in OsmAnd or control the media player with your hands on the handlebars. BT connection and control via integrated Arduino ESP32 D1 Mini processor. For further informations see <a href="http://transalp-freunde-grenzland.de/bt-navibuttons/">this link</a> (german only, sorry). I made it in PLA but other materials like ABS might work as well. Be careful when you remove the supports, espacially the thin edge at the button hole in the back half is vulnerable.
