This is my entry for the ThinkGeek Sci-Fi Contest: a very simple-looking alien test tube or whatever you want to call it. This would be great for putting things on display like an alien doll or a person. However, I would highly discourage filling it up with any fluids (it wasn't made for that). So, here's how I made this apparatus.

I apologize for all the steps. Most of them are pictures just so you could see how it's done. I tried installing dragdropupload on my Firefox, but it was incompatible. So for now we're stuck with a lot of steps that are mostly pictures. I hope you don't mind.

## Step 1: Part 1: Bottom/Top

-Open a new part
-Sketch a circle on the top plane and Smart Dimension it to 2.600 inches.
-Sketch a horizontal centerline that passes through the origin.

## Step 2:

-Select Trim Entities and click on the top part of the circle.
-Sketch a rectangle (1.300 in) and trim the bottom line. The whole drawing should still add up to 2.600 in.
-Next, select Sketch Chamfer and click on both the top corners. Don't bother with the settings and click OK.

## Step 3:

-Exit the sketch and go to Boss Extrude.
-Set the depth to 0.30 in. and the draft to 10 degrees. Click OK once done.

## Step 4:

-Sketch two circles on the top part. The outside circle should be 2.200 in. while the inside circle should be 2.180 in.
-Go to Boss Extrude again and set the depth to 0.10 in.

## Step 5:

-Draw a circle on the top part and Smart Dimension the diameter to 1.900 in.
-Go into Extrude Cut and click on the newly drawn circle. Set the depth to 0.10 in. Save it.

## Step 6: Part 2: the Glass

Now that we got the bottom taken care of, let's move on to the glass cylinder.

-Sketch two circles on the top plane. The outside circle should be 2.180 in. while the inside circle should be 2.160 in.
-Extrude the circles to 2.700 in
-Go to "Edit Appearance" and click on Textures (the checkerboard-patterned sphere in the preview)

## Step 7:

-Expand the menu for Appearance(color) and go to the glass folder. From here, you can choose whichever glass texture you want (I just stuck with the clear texture).

We're almost done. Last thing we need to do is assemble it.

## Step 8: Part 3: the Assembly

-Open a new assembly
-When you open a new assembly, there's a menu for inserting components. Click on the browse tab and bring up the two parts we made.

## Step 9:

-Select one of the parts and click on Rotate Component.
-Rotate the part so that it's upside down but still matching with the other (i.e. flat areas are parallel). I can assure you'll find yourself changing the camera angle a few times.

## Step 10:

This next part is basically mating the whole thing together.

## Step 15:

And that's how we do it! I know it's another simple invention, but it's all I got. Another thing you could do is find a glass cylinder and measure it out. Once you get all the dimensions, you can make the parts. Again, I apologize for all the steps.
شكرا على الشرح
Apart from the lack of textures this looks great, and after all SolidWorks comes with some materials at least. Good job, and simple to recreate. <br> <br>But you could mate the lid with the body - use a concentric connection on the glass and the matching face on the lid. It will put the lid in the right position. Then use a parallel connection on the flat faces at the back (from this angle at least) of lid and bottom, this will keep the lid in the right position rotation-wise. Now you should be able to move it up and down when you drag it. <br> <br>If you want to go a little further you could use a limited connection - I don't have SolidWorks installes in english, so I'm not sure about the exact name, but it's in the second tab of connections I think. There, you chose the upper face of the glass and the matching one on the lid, and set a minimal and maximal distance. Now you can still drag it, but it will stop when closed or then opened far enough.
