[0:01] So, I’ve started a new project.
[0:04] This will be a glowing moon lamp.
[0:07] This will consist of several bits of work.
[0:11] The first one will be actually printing the moon.
[0:16] Then we’ll build some electronics and then we’ll build a base and then finally we’ll
[0:23] assemble the complete glowing moon.
[0:25] We’ll start off by printing the moon component of the lamp.
[0:31] The first thing we’re going to need is a moon model for our lamp.
[0:36] If you go to thingiverse there’s already a really nice NASA CGI Moon Kit 2019 moon lamp.
[0:44] And this already has some really nice files that we can reuse.
[0:48] I’m going to use the 5 inch moon.
[0:51] So, I’ll download this file and then we’ll prepare it for printing.
[0:58] Now, it’s a bit too large to manipulated inside fusion 360 so I’m going to use Blender to
[1:08] prepare it for printing.
[1:10] I’ve launched Blender and created a new file.
[1:14] It starts off with a box as default.
[1:17] So let’s just select that and delete it using the “X” button.
[1:22] And now we’ll import our moon model.
[1:25] We go file import STL and then let’s find our moon lamp and import this file.
[1:34] This can take a few moments to import because it’s quite a complex file.
[1:46] Our moon has been imported, we’ll have to zoom out quite a bit to actually see it.
[1:52] So let’s zoom out.
[1:54] And there you can see we have a pretty nice moon.
[1:59] What I want to do is give it a flat bottom so we can print it.
[2:06] And also cut out a hole so that we can slide this over our heat sink and LED.
[2:12] The first thing I’ll do is give it a flat bottom.
[2:17] What we’ll do is add a cylinder.
[2:20] So you can see here we have the add cylinder.
[2:26] We’ll bump up the number of vertices.
[2:29] Let’s make that 128.
[2:31] Our radius.. so I know that my heatsink is 50mm diameter.
[2:39] We’ll have a 5mm gap around that so 2.5mm all around it and I’d quite like a lip of
[2:52] 5mm.
[2:53] So that’s 50+5+5 on each side will be 65mm in diameter.
[3:01] So, 65/2 is 32.5mm.
[3:05] For our depth we’ll just make this 5mm deep.
[3:13] That’s our cylinder added.
[3:16] Let’s move it into the right position.
[3:18] So we’ll pick the move command.
[3:21] Now we can move our cylinder down to the bottom of our moon.
[3:26] Looking at this I think probably around about there.
[3:35] We’ll need to obviously clean this bottom up and cut the hole.
[3:42] First of all let’s combine our cylinder.
[3:45] No, let’s cut out the hole for the heatsink.
[3:50] So, let’s add another cylinder.
[3:55] Add -> mesh -> cylinder.
[3:59] And this time we’ll do 55mm diameter so that will be 55/2 - which is 27.5mm.
[4:10] This time we’ll make the depth quite large because we’re going to use this for cutting
[4:19] things out.
[4:20] So a depth of 20.
[4:22] And now let’s move this down to here.
[4:27] So you can see it will slice through our other cylinder and the moon.
[4:34] Let’s do the slicing.
[4:36] We want to combine the moon with our first cylinder and then cut our second cylinder
[4:44] out from that object.
[4:46] We go into the modify properties and add a boolean modifier to the moon object and we’ll
[4:56] do a union with the first cylinder we added.
[5:04] Let’s apply that.
[5:06] And then we’ll another boolean modifier.
[5:14] This time we’ll take the difference and we’ll use the second cylinder we added.
[5:21] And apply that.
[5:25] Now let’s delete the second cylinder.
[5:30] So we’ll select it, hit the X button and hit delete.
[5:38] And then we also delete the first cylinder we added.
[5:45] So select it, hit “X” and then delete.
[5:50] We’re almost there with modifying our moon.
[5:52] We can see there is still some rough parts on the base of our moon.
[6:00] So what we’ll do is we’ll quickly clean up those.
[6:03] So we’ll go Add -> Mesh -> Cylinder.
[6:07] We’ll just add any radius provided it’s big enough.
[6:14] And depth can leave as 20.
[6:17] So let’s move this down and we’ll place it so that it just overlaps our bottom cylinder.
[6:29] And then once again we’ll apply a modifier to our moon lamp and do a boolean modifier
[6:41] and take the difference between this new cylinder we just added.
[6:47] Hit apply.
[6:49] And now we can delete this cylinder as well.
[7:01] So, X, delete.
[7:05] Now you can see a perfectly smooth bottom to our moon and we have a hole for our heatsink
[7:16] and LED.
[7:17] What we can do is we can now save this to an STL file.
[7:22] So we go File -> Export -> STL and we’ll call this moon-with-hole.stl
[7:34] And we hit “export”
[7:52] So that files now exported.
[7:54] We can switch into Cura and load it in.
[8:04] So let’s do File -> Open File and load our moon lamp.
[8:20] Open up our moon with hold stl file.
[8:24] And it’s loaded in our model.
[8:26] We can see it should print.
[8:28] Now for the print settings we need to set the infill to 100%.
[8:36] So our infill density 100.
[8:39] And I’m going to print using a brim just to make sure it does stick to the print bed.
[8:47] So lets find our support…
[8:58] Actually lets find our build plate adhesion and we’ll change this to brim and I think
[9:04] that should probably be ok.
[9:09] So now let’s slice.
[9:20] We’ll save to file and then we’ll print.
[9:51] So that’s our print complete.
[9:54] It’s come out pretty well.
[9:57] No issues with extrusion.
[10:00] In the next video, we’ll start looking at prototyping the hardware for actually shining
[10:08] the light inside of the lamp.
[10:10] See you next time!
