Hello, this is my first instructable, I hope you like it.
A few months ago I built a 3D printer and since then I started to design pieces useful for me and I think it may be also useful for anyone.
The design that I show you is a threaded funnel that is placed in the deposit of a rototiller. This makes it easier to fill the tank with gasoline without spill any drop.
Then I am going to show you how I did it.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Design
To design the funnel I used the program Solidworks 2015.First I took the measurements of the thread to fit in the tank. Then I gave the funnel measures that I found appropriate.
Step 2: Repetier Host
I saved the file with the STL extension and I opened it with the program "Repeiter Host".
Then I set the parameters as shown in the picture.
Here you are the STL file to print it directly.
Step 3: Printing
The impression lasts about 7 hours. It can be done in much less time if you do not want so much quality .
In the pictures and videos you can see how the impression is made .
Step 4: Finished Project
After 7 hours, the funnel is finished .
It fits perfectly into the fuel tank .
Looking forward to your comments and questions.
