@3sheds , very good of you to share your method of aligning the magnets. I had used the same method, but I forgot to write it down in my earlier post.
Another update!
The cable tie I'd attached to help pull open the flap has snapped. My guess is a stress fracture occurred from the wind buffeting and repeated pulling of the tie to open the cover. I fitted it in the winter too, so the cold weather may have sped up the fracture process.
Anyway, I've now made my third attempt to find a good solution for opening the cover. After the cable tie had broken, I did find that I could use my finger tips to pull the flap open, but I wanted something to pull if required. The magnets are strong enough to keep the flap closed until the port locks when the car is locked or starts, the bond is weak enough to prise with fingers, but I did think that in cold weather this may be more tricky and also sometimes the cap seals more securely and does need more of a tug to open.
Anyway, I removed the cable tie stub and attached some garden twine I had in the shed (the non-eco stuff made from PPE plastic - I'll be compost long before it has biodegraded) Some decoration was added to the twine as you can see in the photos. I made the mistake of it being legible when the charging flap is open, it's back to front once it is closed. I sealed the ends of the twine with super glue to help prevent the knots coming undone.
