This stand was designed to fit the phone with the official "Flip Cover with Pen" on it - however, you must slide the pen holder off the back (slide it up to remove it, kinda like a joycon). There is a slot on the base of the stand for the pen + holder. The lip at the front is just tall enough to secure the phone while still allowing access to bottom navigation.
For the wireless charging pad itself, it's a slightly tight fit but very secure as a result (I plugged in the cord first, then pushed it in from the front rather than trying to slide it from the top). Fits this wireless charging pad very well:

There are some imperfections in the design - such as the surface is a bit uneven, and the extended part of the stand is not aligned with the wireless charging mount - I just hacked it together with TinkerCAD but measured it out as best I could! Also, you might be able to get by without supports, but specifically the first few layers of the part holding the wireless charger are not connected to the rest, so it's best to include them for at least that section.
