I have Fold4 and been looking for QuadLock cases, but am afraid device is too heavy to be mounted on something like bicycle or motorcycle. For mounting in cars, sure I can see it being used.

I printed it and attached the mag quad ring. https://www.thingiverse.com/make:1141679
It is very secure with the 3m transfer tape (snapped on pretty good without it, but i want to make sure its solid) l, and honestly works much better than my previous magsafe setup (oh snap 3.0). Wireless charging works fantastic, doesn't interfere with pen (when there aren't any magnetic accessories attached), and surprisingly wireless power share works.
I'm comfortable putting it on my bike at this point; however, I am going to put a skin on the case -- I don't like the blue alone, and I'm not sure how well PLA alone holds up to a drop.
PLA is pretty brittle but rigid. So it won't easily let your phone out of the case, but should it fall, I fully expect PLA to crack. PET-G is complete opposite. Elastic but strong.
If it breaks I will try to print out of petg. I may have to print somewhere else, because the printers I have access to I'm only allowed to print PLA AFAIK. I'm hoping the skin (besides looking cool - it's an xray image of the phone) also reinforces and buffers any impact/fall.
Well, I'll let you know how it works once I actually make it.
I'm not that concerned about the case sticking to my phone, as long as the dimensions are right,. I have this very thin double-sided 3m adhesive (ACIT 3M 468 MP, Double-Sided Transfer, 5 Sheets (10'') https://a.co/d/4F0DrF3) - it's essentially the same thing that is in random consumer product made to stick to walls, phones, etc. I actually have it holding my current magsafe adapter to my phone (I moved it from a different case) and it's pretty solid.
Now-- my fingers are crossed that it holds to the mount well AND the mag ring works and charges well.
