I've been interested in carnivorous plants since I was a kid, but I haven't had any for about a decade. Recently, though, the idea of growing a venus fly trap in my dorm room hit me. There were a few issues I had to overcome before growing one, though. There are three major environmental factors venus fly traps require: high humidity, lots of light, and a nutrient-poor soil watered with distilled water. The soil is an easy problem to solve. Humidity is a bit trickier, but even in a place a mile above sea level as long as the terrarium has relatively small openings for air the humidity stays high enough inside. Light is another big issue. I don't a whole lot of sunlight through my window, so I integrated an LED light source into the terrarium. I have it running on a timer 10 hours a day, so between this and the sunlight I think it's getting the rough equivalent of a day of direct sunlight.
I designed 6 interlocking panels in SolidWorks that together comprise my terrarium design. My design calls for the sides to be laser-cut from 1/4" acrylic. The interlocking design gives it a cool look, makes it a lot easier to glue the terrarium in the right shape, and gives it a better seal when complete.
Step 2: Laser Cutting
I used a 100-watt Epilog laser cutter my college has to cut the panels from 1/4" acrylic. The design was intricate enough that any other cutting method would take longer and not give as nice results. Using the laser cutter, the panels came out with very clean, accurate lines. This made the final terrarium look very nice and helped the pieces interlock correctly when I glued them together.
