CMF P2P with print in place collapsible popsocket

Archimedis2002 proposed the popsocket and I integrated it in the CMF Phone 2 Pro Cover. For printing Instructions of the popsocket, please refer to the original model. The backcover here has been thickened up to be able to print it on the backside. If you want the slimmer version that might need supports you will also find that in the files section.
