The stand can be used to set the phone in 4 positions. Phone be placed in landscape and portrait orientation. The is a cut out in the middle is for the charging cable to pass through with two chambers directing the sound from the bottom firing speakers towards the user.
V1.5 - Slight modifications were done to the Base to improve the notches for the support. The Center has been modified with larger chambers for sound and for easier printing. The mounting of the Center to the Base is also easier. The Support piece is largely the same with longer rods for the lower end.
For V1.5, the only area which might require supports are on the inside of the speaker chambers. The slot for the USB cable can be printed without support.
Center V1.6 - There is a cutout to hold the USB cable when not in use and some modifications to the USB cable slot.
White images are V1.5
Supports can placed on the build plate alone.
