So, I've started a new project.
This will be a glowing moon lamp.
This will consist of several bits of work.
The first one will be actually printing the moon.
Then we'll build some electronics and then we'll build a base and then finally we'll
assemble the complete glowing moon.
We'll start off by printing the moon component of the lamp.
The first thing we're going to need is a moon model for our lamp.
If you go to thingiverse there's already a really nice NASA CGI Moon Kit 2019 moon lamp.
And this already has some really nice files that we can reuse.
I'm going to use the 5 inch moon.
So, I'll download this file and then we'll prepare it for printing.
Now, it's a bit too large to manipulated inside fusion 360 so I'm going to use Blender to
prepare it for printing.
I've launched Blender and created a new file.
It starts off with a box as default.
So let's just select that and delete it using the "X" button.
And now we'll import our moon model.
We go file import STL and then let's find our moon lamp and import this file.
This can take a few moments to import because it's quite a complex file.
Our moon has been imported, we'll have to zoom out quite a bit to actually see it.
So let's zoom out.
And there you can see we have a pretty nice moon.
What I want to do is give it a flat bottom so we can print it.
And also cut out a hole so that we can slide this over our heat sink and LED.
The first thing I'll do is give it a flat bottom.
What we'll do is add a cylinder.
So you can see here we have the add cylinder.
We'll bump up the number of vertices.
Let's make that 128.
Our radius.. so I know that my heatsink is 50mm diameter.
We'll have a 5mm gap around that so 2.5mm all around it and I'd quite like a lip of
5mm.
So that's 50+5+5 on each side will be 65mm in diameter.
So, 65/2 is 32.5mm.
For our depth we'll just make this 5mm deep.
That's our cylinder added.
Let's move it into the right position.
So we'll pick the move command.
Now we can move our cylinder down to the bottom of our moon.
Looking at this I think probably around about there.
We'll need to obviously clean this bottom up and cut the hole.
First of all let's combine our cylinder.
No, let's cut out the hole for the heatsink.
So, let's add another cylinder.
Add -> mesh -> cylinder.
And this time we'll do 55mm diameter so that will be 55/2 - which is 27.5mm.
This time we'll make the depth quite large because we're going to use this for cutting
things out.
So a depth of 20.
And now let's move this down to here.
So you can see it will slice through our other cylinder and the moon.
Let's do the slicing.
We want to combine the moon with our first cylinder and then cut our second cylinder
out from that object.
We go into the modify properties and add a boolean modifier to the moon object and we'll
do a union with the first cylinder we added.
Let's apply that.
And then we'll another boolean modifier.
This time we'll take the difference and we'll use the second cylinder we added.
And apply that.
Now let's delete the second cylinder.
So we'll select it, hit the X button and hit delete.
And then we also delete the first cylinder we added.
So select it, hit "X" and then delete.
We're almost there with modifying our moon.
We can see there is still some rough parts on the base of our moon.
So what we'll do is we'll quickly clean up those.
So we'll go Add -> Mesh -> Cylinder.
We'll just add any radius provided it's big enough.
And depth can leave as 20.
So let's move this down and we'll place it so that it just overlaps our bottom cylinder.
And then once again we'll apply a modifier to our moon lamp and do a boolean modifier
and take the difference between this new cylinder we just added.
Hit apply.
And now we can delete this cylinder as well.
So, X, delete.
Now you can see a perfectly smooth bottom to our moon and we have a hole for our heatsink
and LED.
What we can do is we can now save this to an STL file.
So we go File -> Export -> STL and we'll call this moon-with-hole.stl
And we hit "export"
So that files now exported.
We can switch into Cura and load it in.
So let's do File -> Open File and load our moon lamp.
Open up our moon with hold stl file.
And it's loaded in our model.
We can see it should print.
Now for the print settings we need to set the infill to 100%.
So our infill density 100.
And I'm going to print using a brim just to make sure it does stick to the print bed.
So lets find our support...
Actually lets find our build plate adhesion and we'll change this to brim and I think
that should probably be ok.
So now let's slice.
We'll save to file and then we'll print.
So that's our print complete.
It's come out pretty well.
No issues with extrusion.
In the next video, we'll start looking at prototyping the hardware for actually shining
the light inside of the lamp.
See you next time!
