I don’t think that would make difference. Yes, they are close together and meaningful bumps would weaken the case at that point, as I tried to point out. It’s about how thick your fingertips are and how often you use them [switches] - some will be fine with how the hole is now.

Woah, I-LO-VE-IT, this is exactly what I wanted to achieve in terms of design.
The imperfections are minimal compared to my TPU shell and your shell doesn’t feel like a very thick block at all, unlike mine.
I’m following the evolutions very closely but it makes me really want to reprint a TPU shell

Hello, this is not so exotic, if I understood well it is a HP technology (patent ?) allowing fine-grained materials that can do ultra-thin layers (so you shall not see them).
Its application is mainly a “final prototype” product or small series before injection molding for instance.
A few 3D printers service propose this technology.

OK, I hope I’ve transposed all your suggestions. Here is the new model
- Increased side thickness by 0.5 mm
- Increased bottom thickness by 0.5 mm
- Increased length by 1.5 mm
- Increased side holes by 1 mm (towards the bottom)
- Split bottom hole into three
- Adjusted camera and led positions
- Adjusted audio jack position and diameter
- Added splits to the bottom

Thanks, excellent! I’m going to go for 0.14 printing tomorrow, in black. Should look nice.
About the splits though: you have them (if Slic3r shows them correctly) at the corners towards center line at 45 degree angle. I think it might work better to have them aimed along the top inner edge. Possibly something to test later.
Also, I’m, pretty sure they need to be longer (10-30mm possibly), but I’ll have to test that out and estimate it with the new thickness and all - minor surgery again. They need to allow enough bend to insert L5 but be rigid enough to keep it tight. We’ll see.
Oh, and I had time to do a little rapid development with a saw and minor surgery with a crafts knife. Patient is… alive! 
I turned the grey prototype to the orange v.2 type case. I sawed off the ends (leaving the corners and back edges to top and bottom) and now the sides grip the phone nicely (very snug, well designed - thanks againg @fiacco!), all while allowing the rigid material to flex enough for a MUCH more convenient insertion/removal. First impression is that it might work well and this model will benefit from the increase in thickness.
[edit to add: one more benefit of the v.2: it would be simple to attach a wallet/book type (faux)leather wrap to a phone with that holding it - if anyone likes that sort of cases… could probably find a suitably sized wallet/book case and swap the holder part]

Shouldn’t - it works now for me. Something else wrong?

Straight splits attached, you can choose. I was pretty undecided, but the 45° version looks nicer so …
It’s worth noting that +1.5 mm on the length is a huge change, I couldn’t be off by that much, I think it will be pretty slack now.
The open shell looks nice, but not very protective. I’m for the rubber all around, according to @prog-amateur idea

Send allows a maximum of 20 downloads, maybe already reached? Do you know a better file transfer solution?
Edit: just checked, still 17 remaining, must be something else

The length is probably 0,7-1,0mm short but the rigid is so snug that the extra 0,5 is no problem. This is probably a thing that needs experimenting with that TPU/rubber printing too, to get it just right. The rough draft version may also have had some heat deformity or rough surface to skew measurements. For that extra space, I can always insert a piece of fabric or something, which will act as cushion, if it comes to that. I’m hoping the next prototype tomorrow will tell more. [edit: it may take me until the night or until Sunday to update, not sure how it goes]
Ay, there is a tradeoff - particularly with rigid material - between protection and convenience on those designs. Maybe someone will find a third alternative, or fourth. TPU/rubbes has its benefits, but I’d really like a hybrid, that has a rigid body with bumber corners…
And thanks again for the quick modifications!

I also think your 1st release is the best for flexible material like TPU.
I was thinking about something… what about REAL silicone ?
I mean, we have a case shape, based on it, we could make a mask / mold that opens and closes and that we grease to avoid that the silicone that we would pour through a hole does not adhere to the mold?
What do you think, is it realistic ?

I think TPU will benefit from the changes too, to have everything well in place (just remember to remove the slits for that version). On the other hand, I’m also pretty sure there are some minorfixes needed after the first prototype too (even if it’s already usable).
I had the mold idea too but not the skill. Someone could also print a mold directly (invert the model in a block, i quess, and add holes to push material in). But standard latex won’t last long - you’d need to research something better (that’s not very hot, as that would warp a printed mold).

Not the “DIY” in my opinion.
I’ve found this website: https://www.protolabs.com/ they offer a huge range of materials and technologies. I think they could do prototypes as well as small series, they have facilities in the United States and Europe. I will ask for an offer as soon as I have a good model for an elastomeric case.
Absolutely. BTW, since you removed the top from the first prototype could you please check the matching of the internal profile with the phone? Just by placing the little piece on the side of the phone ans see if there are clearances …

put that on ebay or amazon and I am buying it. Give it an adjustable kickstand piece, I will even write a positive review!
