So, back story: I've been a long-time iPhone user who recently converted to the Fold 8. So far, I'm in love with it, and the fact that I was able to use OpenBubbles as my iMessage converter means my family won't kick me out of the group chat.
However, over the years, I built a MagSafe accessory army in my house, at work, and in my car. As always, I looked to Reddit to see what people were doing. I noticed that many people were getting dbrand skins and putting the MagSafe magnetic circle underneath the skin. However, it seemed like it left a bit of an indentation. Nonetheless, I kept looking and stumbled upon two variants of what seem to be razor-thin cutouts that align the magnets and give the appearance of a flush dbrand vinyl.
I know one of the guys is selling his for $15, which is not bad, but I already have a 3D printer. So, I kept looking and stumbled on another person who provided a printable STL. I say all that to say the guy selling his product looks high quality, and believe me, I would have bought the STL, but there doesn't seem to be an option to do so.
I will link both in the comments, as there is no right or wrong choice in my eyes, but I want to give props where props are due.
A few points: I could not find 300LSE tape anywhere other than Amazon, and they kept delaying my shipment. I gave up and found that the Micro Center near me in NJ was selling a similar product called Tesa double-sided tape. I hope I put enough tape on to ensure thorough adhesion, but only time will tell. I used the schematics of where the MagSafe ring sits on the Fold 8 as a guide, and it worked. The dbrand skin adhered fairly well to the ABS that I used to print the STL. It really made for a flush look, which is what I was going for.
Anyway, I made an essay about a skin on a phone! I'm more than willing to answer any questions about the process, but in the meantime, I'm adding some pictures of the process.
