This is a phone dock that should fit most modern smartphone with cases on them.
It was modeled in Blender 2.80 using the measurements of the Pixel 3 but it might also work with other phones. Just be sure to check the dimensions if you plane to use this design with an other phone (and leave a comment to let people know the compatibility list :) ).
The dock was designed to hold the phone with a case on it. You could use it without a case on your phone but you will have a less secure fit. I personnaly use the fabric case by Google which was included in my phone box when I ordered it.
I wanted to have a nice way to have my phone on my desk while charging it and was really annoyed by the clutter caused by the charging cable and the phone laying flat on my desk.
So I came up with this design which allows you, not only to hold your phone while charging, but also to run the charging cable below the phone dock.
You can also use this as a regular phone dock and you can store the power brick (EU version, might work with others versions but I did not check) on the dock itself simply by plugging it on the top of the dock. Then you'll be able to use the power brick as a hook for holding the charging cable.
That way you can use this dock while charging or not your phone and in both case your setup will stay perfectly clean. You can use the dock either in portrait or landscape mode.
You might be interested in this other design as well if you own a Google pixel phone:
It is a little magnetic box for storing/displaying your Pixel earphones and it has the same rounded esthetic as this phone dock.
I am doing my best to produce good looking and reliable designs so if you feel like it you can offer me some coffee by tipping me :)
I used a 15% mm cubic infill with a 1.6 mm wide shell (4 walls on my 0.4 mm nozzle).
This printed in 7 hours and used 30 meters of PLA (90 grams).
This piece is designed to print without supports in its final orientation, you'll just have some bridges in the hole for the charging cable but it is not a big deal. Also the angles where designed in such a way that all bridges are a little bit supported by the one before (except for the very first one of course but it is really not a problem).
I personnaly printed this with no brim or raft and no supports an the print went perfectly good (using PLA).
