[#1]

If you want to take one part at a time and discuss how it should be done - we can do that.

In my experience most students who come here lose interest fast in doing it right, but you did come here for a critique, so maybe you are motivated to learn how it should be done.

Which part would you like to start with?

[#2]

Let's start with a nice easy part.

Nut.ipt

Delete the thread feature.

Edit the sketch and add a Vertical constraint to one of the vertical lines.

Notice anything happen?

(the sketch changes color indicating it is fully constrained).

Delete the circle.  Notice anything happen.

Drag the centerpoint of the hex away from and back to the origin center point.

Because Inventor is now confused by the missing circle you might have to re-edit the extrude but simply click OK.

[#3]

Start a new sketch on one of the faces and Project Geometry one of the hex edges.

Sketch a circle tangent to the edge.

e

[#4]

Extude the circle Through All with the Intersect option and click the More tab and set to 45° to add a turned chamfer to the corners.

Repeat on other side.

[#5]

Start the Hole command and set to Concentric.

Click the plane and the circle and set to tapped and size.

[#6]

Add a .25mm chamfer to both sided of the hole.

Change to Chrome texture.

Now isn't that just prettier.  Should make you feel proud!

[#7]

Which part would you like to do next?

[#8]

JD is on a roll! GO GET EM JD!  

[#9]

In addition to JD's comments

M7 is NOT a preferred standard metric thread

So it's either M6 tapping hole of 5mm Clearance hole of 6.6mm actual 7mm nerest drill OR M8 tapping  hole of 6.8mm 7mm nearest Clearancehole of  9mm actuall

NOTE

These are UK nearest Tapping hole size they may vary slightly according to different country's standards & drill sizes available.

Many thanks for the correction
