This is a two-part vase-mode phone stand with an indentation to hold a 70mm round QI charging puck.
It must be printed in vase-mode. I recommend printing at 0.3mm layer height with a 1.2mm bottom.
You will need to make sure that the inside part has the lip at the bottom and that the outside is printed with the opposite side down compared to the inside part.
I plan on filling mine with coarse sand for weight.
This was designed for vase-mode, but works equally well at about 10% infill and in that case you only need to print the outside model.
This was created as a simple solid in Fusion 360.
