Functionally, the design is complete, but as the old saying goes, it's all in the details. This little octopus would be much cuter with a face. Here's how you give it one:
Since this circle will become the face, it's good to name it Face now, using the same steps for naming objects from before.
The Make Edge/Face
command attempts to make a connected face from the selected vertices or lines. It can be quite intelligent, but if the points are not all flat, the edges may twist unexpectedly.
Y
-axis line:Duplicating in Edit mode doesn't create a new object. Whatever is selected is duplicated, but it remains a part of the object it was duplicated from. Points, lines, and faces can all be duplicated and transformed within the same object, even if it looks like they're separate parts. In this way, a face with separate eyes and mouth can be created that will still all be one face object.
Y
axis line:Both eyes are still a part of the face object, even though they're separate. In the same way, objects created while in Edit mode are likewise added to the existing object.
Y
-axis (Y) (about 3 units):The shapes now look like a face, but only in two dimensions. If seen from a different angle, it's clear that the face is very flat. To give it the additional dimensions necessary, follow these steps:
X
axis (X) 90
degrees (90):/
). The face is hidden inside the body, so move (G) it along the Z
and Y
axes (Shift + X) until it's outside the octopus body:Z
axis (Z) until it's positioned properly:Y
axis (Y) until it's partway inside the body:It may help to use Wireframe view to ensure the face is deep enough but not too deep. About four or five small squares' depth (or 0.4
or 0.5
real-world millimeters) is perfect. If it's too deep, it may cut all the way through into the cup space and create an overhang problem. The top of the mouth will rely on some bridging during prints, and that's okay.
Your octopus pencil holder is now complete.
Select the body, and in the Info Panel menu (at the top of the screen), go to File | Export | Stl (.stl) to export the 3D print-ready octopus holder. Be sure to choose a directory where you can find the file later in order to send it to the printer.
