Summary

I designed it to be printed in transparent PLA, monolayer, about 8 cm wide, then you can put a Tillandsia inside as tentacles and fix it to lamps/ceiling with nylon wire.

It prited well.

Instructions

Print it as a single wall, spiralized, no infill, open top and bottom shape, with transparent or transparent/colored PLA.

Then buy a small Tillandsia like this one: http://img139.imageshack.us/img139/8257/jnsy2.jpg

Fix it, through ceiling holes, with a rubber band.

Tillandsiae grow even upside down, and need just rare water spray to stay alive. Read about them, if you do this, and please post a picture!
