2-size lens case for canon EF-S 18-55 and 75-300

Telescoping case to hold canon EF-S 18-55 f/3.5-5.6 IS STM and EF 75-300 f/4-5.6 III lenses. Perfect for anyone who bought the EOS100D "Get closer kit" in the Black Friday sales with Canon's winter cashback offer. Anyone? It can't be just me....
Anyway, print both bits, and add some foam inside.
Twist to lock in 2 places to hold whichever lens isn't on the camera, without taking up more space than it needs to.
