etrex belt \ backpack clip

thingiverse

You'll need to get a clip for attaching the etrex 20 to your backpack's chest strap or loop for quick access while on the trail. Instructions To print vertically, I didn't use raft or supports; 100% infill, .2 layer thickness with 2-3 shells will suffice. When you're done, cut away any "drawn-in" support that may have developed during the printing process.
