Base for car phone mount, molded to 2015 Odyssey

I needed a flat spot to attach my phone charger to my Honda Odyssey. So I 3D scanned part of the dashboard then created this base that the phone holder can stick to. Tips:

• This will probably work with 2011 to 2017 Honda Odyssey dashboards.
• The (recessed) flat surface circle is 79mm in diameter. So the charger must fit this flat surface.
• Use 3M brand very heavy bond “VHB” double sided tape to attach. 
• Use a filament that won't melt in the summer.
