New to OnShape and CAD in general

Hello Everyone

I am trying to create a top piece for a race drone that will protect the camera and house a receiver and video transmitter.   I have the basic shape, but I am stuck on a few things.  

Firstly here is the link to the project  https://cad.onshape.com/documents/94e3510999ab8a61cfed5c1b/w/69df2d67275b25f368368be9/e/f6e1e832ac5d8958ccf0c0ed

Ok so issues I'm unable to resolve:

1.  There is a sketch entitled 'bottom plug'.  How do I make this 1.5mm thick and place it on the bottom of the directly below where the sketch is under the rectangular hole?

2.  There is a sketch entitled 'antenna hole (r)'.  How do I make a post with a hole 3mm in diameter with a 1mm wall 45 degrees to the face of the wall, and how would I repeat that for the other side?

I plan on printing this with TPU. if that makes a difference.  Any help/advice would be greatly appreciated

Thank you

Chris

1: You can change the sketch plane to the bottom surface of the square hole
Then do an extrude add, don't forget to select your merge scope, otherwise leave New selected and a new part will be made


2: Create a new plane at 45° using the "line angle" option

From here drag the plane so it is above the antenna hole sketch


Now edit your antenna sketch an select Plane1 as your sketch plane
and dimension your hole accordingly


Now do an extrude->New->up to next


Now create a new plane using the "Mid Plane" option and select the two inner walls


Now select Mirror-part mirror->new and click your antenna mount, then plane2.


From here use Boolean Union to add the pieces to the main body to make them joined as the same part.
I assume you want this whole thing to be one part. In that case you may need to set your extrudes from before to "add' rather than "New". If that is not what you want, then you can skip the boolean add step.
