After getting tired of feeding cables through glands into enclosures only to have to cut off the connector again to get the cable out, decided to make something that neatly protects the cable and electronics inside the enclosure but still allows the cable (with connector still attached) to be easily removed.  Not really designed to be waterproof but is weather resistant to an extent. Designed for a specific plastic enclosure with wall thickness of less than 2mm but could easily be made for any.  Works brilliantly and looks tidy. Happy making! Made using ABS at 0.2mm with course support.  Use whatever foam you like as the compression material.  I used pre-perforated light density foam so it forms around the cables nicely.
