I could not find commerical cases that provided enough impact protection (all too hard) and was also comfortable to hold in the hand. I also wanted an outer sleeve to put the phone and case into to protect the screen better.

Case has honeycomb cooling holes too so battery does not get too hot when charging.

Case printed in TPE85A @ 20mm/second, 0.2mm layer height (infill 20% for lower 10 layers and 0% for the upper layers - for soft feel & best corner protection). First 3 and last 4 layers printed solid. Wallls are 3 perimeters thick (04.mm mozzle). Support used.

Sleeve printed in PLA in 2 halves and glued together (0.2mm layer height). Printed solid, no infill. You can also print in one piece.

Friction fit lid for the sleeve printed in TPU98A (02.mm layer height). Fits into the sleeve by flexing slightly. Will not fall out.

The power and volume buttons are made to stand just proud of the case so you can locate them in the dark. They can be glued in place or just pushed into place - mine have stayed put (in fact is best to print them with a little bit of 'elephants foot' to help them stay in place with no glue.

I use an after market magnetic connected charging cable - so have sized the charge hole to prefectly fit the adapter piece.
