“I think that percentage is 100.”
“I would say the same about rectangles, but you get banned if you say rectangles. So rhombuses it is.”
Not all rectangles are rhombuses. And not all rhombuses are rectangles. Don’t be racist and you won’t get banned.
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.
