Thanks! This sounds a lot, but I wanna try making it. I like modifying things to suit my use, and this sounds like a fun learning endeavor. I’ll perhaps look at OpenSCAD. This sounds similar to some of the information I found on blender (making shapes to delete areas). I need to play with these tools to get more facile at doing this.

I don’t have a picture readily availble at the moment, but the stls are www.thingiverse.com/thing:4935721 for the phone case (I just wanna use the right side) and www.thingiverse.com/thing:5704716 for the holder. It’s a little more complex than just a magsafe holder, it has a quadlock mount integrated.
