Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.

Here are closeups of the snap-fit joints on the face and bowl.
Making circular snap-fit joints in Fusion 360 is covered by Noe Ruiz in this video tutorial.
Connect a battery and line up the snapfit parts of the bowl and face. Taking care that all wires are are tucked inside, carefully snap the pieces together.
You might find that the bowl needs some weight in the bottom. If so, some plastic covered ball bearings stuck into the bottom with hot glue should do the trick.
