Let's use the same set screws and copy them and paste. Head Okay, we're going to need to have those we should be able to just paste again. Right click, copy and paste. So now we have two new set screws here and let's put them into place. So let me click there and there see if that worked. Looks like it did it needs to be flipped.

And that looks okay. And let's put the other one into place, assemble joint and that needs to be a rigid joint. Let's double check to make sure that this was a rigid joint that we use so it looks like it wasn't. If I go to joints it should be the last or the second to last joint here. let's right click that and a joint and instead of cylindrical and let's make it rigid head okay. And now we have our two set screws in place on the bottom.

And now we need to drill a hole in this plastic custom piece that we're making. We're going to need to drill and tap a hole which we can have an online machine shop do for us. So let's go ahead and activate this coupler here. Let's go on to the bottom of it and create a sketch. And I want to create a circle again. And we need to dimension it at dimension.

There we go. Let's check our chart again. This is the same chart that we had. And we're going to be creating a half inch hole a half inch 20 threads per inch point 453. Let's go ahead and stop sketch and extrude And we're going to be cut extruding, choose cuts. And in terms of the distance just rotate a bit there.

And in terms of the distance, if we went negative point five let's go negative point four and see what that looks like instead. Let's hit OK. Let's change the opacity on this coupler so we can see through it a little bit better. And if I activate my assembly and pull this up to about where it would be, you can see that we have a lot of space and the top of our hole Let's go ahead and change the joints on this plastic steak like we said to a rigid joint instead of a cylindrical joint. So now that can't move there. Let's change the opacity back on our coupler here to 100%. And let's do the same right now with our top our solar cell holder.

Let's try and simplify our drawing here. Let's get rid of a lot of facts so that we can just see our design Like we said for the solar cell, we're going to need to drill some holes in the bottom of this top in order to get the wires through. That shouldn't be a problem. Now this is going to be 3d printed top. Another thing that I could do as somewhat of a finishing touch here is I could do what's called a fill it on some of these sharp edges. This is another feature, which we didn't talk about, but this this could actually be done with an extrude cut.

It's just a little bit easier with a fillets if I go to modify. Actually, first of all, let's activate the solar cell holder. If I go to modify, fill it and I click on some of these edges. I would just be giving them a radius to make them smooth. And this would make it look a little bit nicer a little bit smoother, makes it look a little bit more like a finished product. A lot of the time sharp edges are not great in designs, but you can see when I drag this arrow, it just simply puts a radius on those sharp edges.

And so we could do a standard fill it of say if we just did point one that looks okay to me and hit OK. So now those corners are rounded off. And then as we said, with our battery here in order to make contact with metal. What we can do is just add some metal clips in here which we should be able to buy pre made. We'll be able to wire our led to the connection of the battery and the battery to our solar cell up top. I can perform another maze just to secure this if I want to right now between there and should be there and that's a rigid match.

And I could do the same with this top, but to be able to take it off and look inside right now, I don't necessarily need to do that I could do the same with the screws. For the screws again, we could just put them into about where they wouldn't be. Here's a much better view of the length that the set screws are going to come through so that should be okay. And I bring my light cover back in. At this point, we are quite close to a full prototype here.
