I have a ghost praying mantis that needed a new place to live, so I recreated the facehugger containment tube from the first 'Alien' movie. I looked at some photos to model it, but didn't go nuts trying to make it perfect. I think it could work to house a variety of small animals, maybe scale it up, add some silicone caulking and put a fish in it? The holes in the top work and printed ok, but honestly should be done away with entirely. It adds a ton of time to the print and doesn't print all that well, I just did it cause I was impatient and didn't have any screen door material laying around. Anyway... enjoy :)
I made this with pieces I had around, but you could totally scale the parts and use something else. I used the following:
- 4" diameter acrylic tube, about 7" long
- 4mm brass rod, cut to about 6 7/8" but just use the right length ya know?? I think it would look better with aluminum rod, but I didn't have any :/
- Print all three parts, the bottom and top need support but not the rim. I printed at .2 layer height and it worked well.
- The parts press-fit together pretty well for me, I gave them tolerance to do this. Your printer might be different so I can't guarenty it will be the same. If you are scared, just scale up the parts by a fraction of a percentage and glue it. But you're lame then.
- Put some eco earth and some twings in there and catch a nasty thing to put inside
