Summary

Love cycling but don't know where you are going? Solution: Bring your GPS with you. Specifically a TomTom XL310 or similar. Uses zap straps for attachment.

Instructions

Download, Slice, Print. No supports, minor bridging, big flat bottom. Got bed stick issues? No problem, warping won't affect the usefulness. Does your printer oversize everything? Whatever, call it an "interferance fit." Scale the model slightly if needed.

Please use a strong elastic band or similar to hold the GPS in place, just in case

Notes:
-The hole in the bottom is useless due to the angled plug.
-You can stick your TomTom in upside down if you prefer for mounting, but you'll have to take it out to turn it on/off.
-SolidWorks file contains a modeled TomTom 310 XL for making other mounts, please note this thing in your derivation.
