A few different versions of jumping spider nests I've made and tried.

One version for clean 90° corners, One version for not so clean corners with, as example, silicon protruding out and one made for just sticking anywhere.

As for mounting them, I have used hotglue to either glue straight to the side of the enclosure or add magnets.

Note: Model 1,2 and 3 make sure your spider is not so small that it can crawl in between the nest and glass. Same if you let your spider hatch its eggs so you don't lose any slings.

Before printing, turn the object to a flat side and print with no support.
