While hiking i used to put my eTrex in my pocket resulting in a bunch of useless waypoints. Then i found a handlebar mount for the etrex which would be perfect without the handlebar part of it, so i decided to try to edit the Openscad file. The backpiece was made in Inventor 2014. This is a remix of Enif's Bike handlebar mount for Garmin eTrex GPS devices: http://www.thingiverse.com/thing:164720
