Tape and snakes do not mix; it's been said soooo many times. This has happened before to people and it shouldn't still be happening, it's avoidable. I hope more people will learn from your experience.
Glad to hear he is okay but please try and augment your cage design so that tape is no part of it, there's no need. Snakes have an uncanny knack at getting stuck. It's a hard way to learn but I am glad you managed to get the tape off, well done!
