This is a case for the Huawei p20 lite with a holding ring on the backside. It works as a popsocket and as a smartphone stand as well. On the first picture you can see a case printed with elastic pla on my anycubic i3 mega.
I uploaded the stl-files for printing, but also the CATIA Part-Files, so you are able to modify details.(I am using CATIA V5 R17)
If you want to use the files commercial, write me a message.
