Phone mount for Trek Bicycle crossbar

thingiverse

This mounts your iPhone or smartphone to the crossbar of a newer Trek bike with a modern flattened crossbar. This fits a Dual Sport 3, but likely fits most modern Trek models. iPhone holder can be tilted to optimize angle of view. Also included is a mounting bracket for older bikes that use a more traditional tubular crossbar design. The two bracket halves don't quite meet, to accommodate a range of sizes, as well as to leave room to tighten the mount to your preference. It is recommended that you use some kind of rubberized tape, like electrical tape, on the inside to aid with grip to the crossbar, thereby eliminating the need to overtighten and bend the brackets. I prefer to use Gorilla Waterproof Patch and Seal Tape because of its extremely strong bond, but any kind of rubbery tape (even duct tape) will provide enough tactile grip. This is a remix of the venerable Modular Mounting System, and the necessary parts are included in this thing. The phone slides in and tightens with ease, able to be mounted and unmounted in seconds. It mounts to the crossbar rather than handlebars to have the advantage of using a cycling computer as well as a phone mounted in easy view and reach. Necessary hardware includes 3 M5 bolts 25mm (even 20mm is a sufficient length) as well as 3 M5 nuts. You can hot glue the nuts into the 3 knobs (Knob_v5) to make them easier to install, but it's not necessary. The Trek Clamp Top as well as the Mount Holder Single require supports because the modular connectors are not touching the print surface. Everything else will print fine as is. I used PLA, but I think just about any material will work.
