Garmin Zumo 390LM Holder

thingiverse

This is a custom mount for the Garmin Zumo 390LM. The clamp is made from 3mm thick material and was printed with three outlines and 20% infill to allow for sufficient flexibility. The fit is quite good - however, you may want to make it less precise in order to fit it into one hand easily. The clamp does not follow the back contour of the device, leaving a roughly 5mm gap between them to accommodate flexing. I also wanted to use an "andobil magnet holder" for my phone that I could reuse for this GPS. The attachment fits well and doesn't require the metal plate to be installed - although I did it anyway, making it very difficult to remove from the holder. You can find the "andobil magnet holder" on Amazon at https://www.amazon.com/dp/B07T7FPK96/. I uploaded both the clamp itself and the adapter for my existing holder. Additionally, I included the FreeCAD file so you can start over where I left off if needed. Have fun modifying it, share your own creations, and let me know what you think of this design.
