If you own a quadcopter chances are you own more than one. It’s kind of an addictive thing in that way. So dig out that dinged up model and build something awesome around it. We’d suggest making it look exactly like a Millenium Falcon. Okay, to be fair this is built around a custom quadcopter originally designed to carry a camera and GPS but removed for this project. We’re not sure if stock models have enough extra umph to lift a fancy fuselage like this (maybe you’ll weigh in on that in the comments?).
As with any great build this started with a scale drawing. The drawing was printed for use as a cutting template for the expanded polystyrene. Part of what makes it look so fantastic is that the fuselage isn’t 2-dimensional. There is depth in the places that matter and that’s all because of near-mythical foam cutting/shaping skills on [Olivier’s] part.
Final touches are LEDs on front and to simulate the curved engine on the tail. You can almost see this thing picking up a handless [Luke] below Bespin’s floating city. This Falcon flies like… a quadcopter (what did you expect? The Kessel Run in 12 parsecs?), which you can see in the videos after the break. The second clip shows how easy it is to remove the foam body from the quad frame, yet another nice touch!
Of course if Star Wars isn’t your thing you can give trolling the skies as a flying body a shot.

One of the issues with extruder-based 3D printing is that it can be very difficult to print objects that have voids in them. You simply must have something to deposit the soft material on until it has a chance to harden. [Matt] found a solution which should work for any extruder-based printer (with one caveat we’ll get to in a minute). He prints a support structure out of HIPS then later dissolves it using Limonene. The image on the left shows the object soaking for 24 hours. The final project is seen beside it.
The only real problem with this technique is that it requires a second extruder. Since printers build objects by layers, switching material in a single print head isn’t an option. HIPS stands for High-Impact Polystyrene. It extrudes at the same temperature as the ABS (235C) and adheres well to a heated bed kept at 115C. ABS will be unaffected by the hydrocarbon solvent Limonene, except for the residual smell of citrus.
So your house looks like a dumping ground for useless junk? Yeah, we know it’s the hacker’s curse… you just can’t stop salvaging stuff. But follow [Pontazy69’s] lead by building something useful out of that junk. He took an old polystyrene box and made it into this fishtank. You can see that the sides and back of the box has gone unaltered, but the front wall is missing. [Pontazy69] marked and cut straight lines while leaving a lip around the edge. Silicone was used to glue some acrylic (or perhaps glass?) to the inside of this lip. Once dried he added another bead around the outside to ensure it doesn’t leak. Few fish would be happy here without some type of filter so he built one of those out of an old plastic bottle and some other pieces. See videos that show you how to build both the tank and the filter after the break.
We love aquarium hacks almost as much as clock hacks. So check out the water exchange system, and a couple of different lighting systems. Then document your own aquarium projects and let us know about them.
