Drain hat for my pipe!

In front of my house, I got a concrete parking space. Before it used to accumulate water in a pound when it was raining, I then took and drilled a hole in center of the pound.  I then drained the water away from the parking space, and into my pluming system.

But then a new problem occurred: The hole I drilled started filling with leafs and other particles like rocks. If the dirt goes into the pipes, this again could lead to dense pipes in the draining system, and that is something that I really don’t want to happen.

So my new solution to fix the problem: I need to create a sort of sieve for preventing all the dirt damaging my draining pipes.

I measured the hole, and I then designed this unit for stopping the dirt entering my pluming.

Designing things with Tinkercad was really easy. It’s nothing like Google Sketchup and Blender (those are the 3D-designer programs that I have tried before). I’m really not familiar with 3D-designing, but I used like 15 minutes to understand the principle behind Tinkercad. And I used about 20 minutes to design the sieve unit.

For the best print, I thought that the best idea was to flip the sieve heads down (180 degrees), because I would generate less support materials for the “palms”. I could probably build the unit without any support, but I didn’t want to fail the first print.

First I sliced the .STL-file with Slic3r. But the print ended badly. What I have experienced is that the raft/skirt on Slic3r isn’t the best, and bigger print sometimes sticks poor to the printer bed. Therefore I sliced the .STL with MakerBots software, MakerWare. I have created a script that does the conversion from MakerBot G-CODE to Reptier-Host friendly G-CODE. I really like the first layer that the MakerWare creates. It’s a 0.5MM thick bed that really sticks to the printer bed.

The palms of version #1 of the product ended up being too high. I miscalculated the height, so I need to create a new design that is lower. But the pipe fitted perfectly in to the hole!
Now I must wait for the rain to start, and then I will see how efficient system is

Just rip off the support.
