I second the comment on the tape. It is not good to have tape in the enclosure. You want to have a hide that the snake can crawl in and feel the walls on all sides, making it a nice cozy close space. I'm not sure your design accomplishes that. Also, if you make a homemade one, be sure that the edges are not sharp. I use a soldering iron to carve out a hole in an old small dog bowl for my first hides. The iron melts the edges and if there is a sharp edge, you can round it off pretty easily. If you go that route, be sure to do the melting outside. The fumes get pretty bad.
