Print guest initials

hey everybody mr gibson i've got a tinkercad tutorial for you today this is um a first introduction to producing parts specifically for 3d printing so we're going to build um we're going to build name key tags with the specific game of 3d printing them at school and getting the parts out to you okay so in our workspace um we're going to be mainly using this text tool here so if you drag the text tool uh onto the work plane um so we're going to deal with just one letter at a time we're not going to simply type our name and we're going to produce each letter of our name or actually i think we're just going to do our initials we're going to do each initial as an individual part okay so i'm just going to type my first initial okay now you can change the font if you like um there's a few font options here i'm going to go for a serif font today okay so that's dead easy that's my first letter i'm just going to use the default sizes it works about right for the product that we're going to use um so if i zoom in on it you'll see the height of this part is 10 millimeters and i'm going to for my first initial i'm just going to keep that okay so i need my second initial so i'm going to drag another text tool in and again i'm going to edit the text that appears to just be my second initial okay now what i want to do is i want to overlap these two parts okay so i can drag my j um to onto my b okay until they're overlapping or interfering okay now where the b and the j are interfering here they start to kind of blur into one so um what i'm going to do is just change the height of the j of my second initial okay so if i click on that uh height tool there and perhaps make it seven millimeters something like that yeah then you can see that it just helps to define the fact that those are two different letters okay the other thing that i want to do is i'm just going to rotate my j very slightly okay so i'm going to rotate here like grab hold of the rotate tool and i'm just going to rotate it a couple of degrees like that okay and you can look around it zoom in on it view it from various different angles one of the good things about this tutorial is that it is really good for practicing kind of looking around a part or an assembly so i need to just check it from various angles to make sure that the two letters are interfering they're not interfering too much okay so my third and last initial okay i'll drag more text into the workplane i edit it okay and again i'm gonna look at it from this angle i'm going to make it interfere with my g with my j rather okay so my j and my g are interfering slightly i want to make sure that interference the overlap is enough so that it doesn't form a weakness in my keying okay and i want the b and the g to be slightly different heights as well i'm going to just bring it down to eight millimeters okay we'll stick with eight minutes yeah i'm going to give it a tiny bit of a rotate so select my g grab the rotate function and rotate slightly at this point i'm just going to move it up very slightly and interfere a tiny bit more so i'm pretty happy with that those three letters they're clearly three different letters i can see if i look from the side i can see they're all different heights however their bottoms are all level the bottoms are all sitting on the workplane and that's important because when we 3d print it we want all three of those letters uh to sit on the build platform of the 3d printer without needing any support okay so i'm happy with that okay now to turn this into a key ring um i'm going to want to give it uh like a ring to put my split ring through so i'm going to take a tube okay so i grab a tube and drag a tube into the workspace now i'm gonna uh i want to shrink it so uh currently the kind of default size for the tube is 20 by 20. if i hold shift and then click on the dimension tool now when i redimension this it'll do it uniformly so i've gone for 12 millimeters for my tube size and then i've placed it so i've got a nice overlap a little bit more get it central on my b yeah so i can see it's central i've got enough overlapping for it to be strong okay if i want to make it stronger i can increase wall thickness look yeah that looks about right to me that's about four millimeter wall thickness okay so i'm happy with that yeah uh this ring looks like it's strongly joined to the b all the letters interfere sufficiently uh the layout of my letters is good so i'm happy with the whole thing as a product so the last thing i want to do is select everything and group it okay so i've selected everything with the selection box i use this group tool up here group it to become all a single object okay that's now a single object and it's a complete piece of data so i'm going to go to the dashboard hitting the tinkercad logo takes me into the dashboard saves all my work okay there's my keyring in the dashboard now yeah um now the next thing i need to do is prepare that data for 3d printing so if i select on that now it brings this screen up and it gives me the options of either going and editing my part in the tingle list or i can download that part if i'm happy with it so i'm going to select download yeah and then i want to select as an stl so that file extension is what the 3d printers will read so if i select as a as an stl file you'll see in the bottom left hand corner of my screen there's my download and i can show in folder and there's my stl file that one of those crazy tinkycad names and now that file there um i can do it as i want okay so i can copy it go into my documents save it in my um save it might save it in a cad folder which i haven't prepared so let's have a new folder so i can't fold it yeah and there it is that file then you can get to me in a number of ways which i'll describe to you [Music] in our online tutorial you can either email it to me or you can submit it through an assignment in teams okay that's your stl file that's the file that 3d printers are going to read which is going to allow us to print your parts okay folks i hope that all makes sense
