This smartphone holder can be easily made with a CNC router.
I have provided the two outlines as DWG files.
I used a solid beech wood panel (18mm thick).
You need 4 cuts, two for each DWG file, then join the parts with vinavil glue.
I have provided the STL file as well, just in case you wish to make this object using a 3D printer.
My build was done on a desktop cnc-machine by Stepcraft using a spiral-toothed 3 mm flute. A coat of oil intensified the wood structure and colour.
Consider a small donation 1€ if you like this design. Thank you.
