Hello !
Some updates here 
- The 3D printer used is the formlabs “form2”, little bigger than the “form1”
- My contact in the ReLab is ok to print others transparent cases for us, that I can then deliver…
However… Unfortunately, the material is not so durable, my case already passed away 
. I accidentally made it falling from my nightstand, approx 50cm height… And here is the result !
The UV resin material is not that resistant, because I had some similar falls with my regular case, without a scratch…
So…
I can print some new transparent covers for the people wanting it, but at your own risks: you have to know that the material is very brittle !
