I fixed the model found here : https://www.myminifactory.com/object/3d-print-stargate-display-for-google-home-mini-85236 . The holder now has a deeper slot to accommodate the StarGate and the StarGate itself is now sized properly to fit. I know these are old now but I still have one and was annoyed that this existed in an unusable state. So here are the fixed models I used.
