Out Front style watch mount for Bike Handlebar

prusaprinters

I've got a Coros Vertix band on my Garmin Forerunner 945. While a super comfy combo, the nylon band made it so I couldn't use most watch mounts on my bike. I got tired of twisting my wrist while on my bike to see my watch, so I designed this mount. I use it indoors on my trainer; if you were to use this outside on something that sees vibrations I'd suggest a rubber (maybe TPU) collar between the mount and the handlebar to prevent the mount from rotating down. I'd also suggest a safety strap. This seems like a good place for this: disclaimer: I'm not responsible if use of this design causes damage to your bike or watch or you. It's not the most sturdy mount out there and will rotate if used without a rubber sleeve on the bar, so I probably wouldn't use it outdoors. Fits 1" handlebar. This requires a square M3 nut (I used McMaster PN 97258A101) and a M3x30 screw (I used McMaster PN 92625A110). The model has fairly tight fit on the print in place hinge (0.005" [0.127 mm] radial clearance). There's a divot on the top to clear the optical HR sensor. This will fit a FR945. It'll likely fit a watch with a smaller lug to lug distance. A larger watch may overhand and not fit well. All side buttons are accessible.  The square nut is inserted into the slot until it bottoms out and aligns with the hole for the M3 bolt. There's a thru hole that can be used to push out the square nut, if you ever need to remove it for some reason (this hole is conveniently sized to fit a M3 bolt).
