Comment on Does anyone use a phone without a protective case?

I 3D printed my phone case. I had considered going without a case, but the Snap 4 Luxe, which I absolutely love, adheres better to cases than the bare phone. That could be my fault, maybe I didn’t clean the phone or adhesive properly, but if I have the phone on a magnet sometimes the Snap stays behind.

So I found a case design someone else made, brought it into Blender (because I don’t know CAD), thickened the back to the same distance as the Snap, then made a hole for the Snap and made sure to include a lip to cover over its curved bezel. I printed the first few layers in a tough 68D TPU, then switched to a 95A TPU for the rest. The tough layers and the lip keep the Snap held to the phone even when the adhesive fails, and the softer TPU makes the case easy to put on and remove.

(This is like, my seventh iteration of this case, and it sure seems flawless for the past few weeks.)

This lets me use the Snap with as little wireless charging distance as possible. I found that some cases added to the inherent 2.5mm of the Snap are just too much distance to reliably charge using weaker qi chargers. With this setup I can wirelessly charge much more reliably! And since I thickened the back of the case, the magnets on the Snap now sit flush with the rest of the back, making qi2-based external batteries more manageable.

Get the loctite glass glue and place a few dots around to help with adhesion but nott too much that it is permanent when you want to remove it.

I personally sprung for the ESR magsafe hololock ring because I wanted it to be as flush as possible on my Samsung S25 Ultra. Being slim but still help with attaching to magsafe products is nice, especially since I live in a place that gets hot, I bout a qi2 car charger that has a peltier cooling unit in it. Phone is ice cold when I slide it off the charger

Side note:
popping it perpendicular to the surface has shown me that without the loctite glass glue, the ESR magnet ring will stay on the charger. So I just make sure to slide it off horizontally.

  I did the perpendicular thing for a while, but two of the magnets I use with the phone (one a charger, one just a mount) are strong enough that removing the phone perpendicularly is difficult.
  
  If I ever decide I don’t want my printer case, I’ll try the loctite solution! Thanks!

    My sister has that snap 4 luxe type item from Amazon and it definitely has such a strong magnet that even attached to the case, it will stay stuck on the wireless charger haha, but I doubt the peltier cooling as effective at keeping it cool because the case is quite thick with snap 4 luxe increasing thickness too. While for my case less phone with only the slim magsafe ring, it is working really effectively at cooling the phone.
    
    I tried those slim frameless cases that had a magsafe ring embedded, too. Unfortunately they were a complete failure. One issue is that they break on the corner that has the S-pen, and one case in particular would fail to stay attached on the phone properly. I wish they were made properly but they were epic fails.(The other case had a metal plate for the magsafe notch, fails at preventing product from twisting)
    
    I looked at those frameless types but they are made of metal and would affect wireless performance. on top of that the design made me feel uneasy.
