Bike top tube Support for Garmin Etrex

The e-bike handlebars are crowded with various media (lights, etc.), therefore I designed this support for my Cannondale Tramount with its elliptical cross-section of the top tube (49 x 39 mm). The design can easily modified for other cross-section.
To improve the adherence between GPS and support, you can use 2 or 3 adhesive tape strips (see picture 3)
The design work well with GPS GARMIN Etrex 30 and similar.
