I just found, printed, and tested this, both the latest version as well as the tablet-mode version. The regular version works perfectly! I only got my P9PF yesterday and the case hasn't arrived for it yet (Pitaka aramid fiber case with built-in Magsafe), so I can't confirm whether or not it works with that case, but it's an ultra-thin case and there's plenty of space left around the spacer, so I am confident it will fit.
The tablet-mode one kind of works. Since the device is so thin in tablet mode, it is too far from the lip for the lip to hold it steady and in contact with the charger. However, even when using my hand to hold it in contact when in tablet mode, though it does charge as expected, the P9PF doesn't engage the "Pixel Stand mode" features, such as photo frame, smart home controls, media controls (if media is playing), etc. So that's a bummer, and of course no criticism to this design, just an FYI for anyone else reading this.
Thanks so much for this awesome and useful print, Hydra! ^_^
Update: Just got my Pitaka case and tested it with this spacer, works perfectly! Just in case anyone else has or wants this case and was wondering. (edited)
