Make Base Mold

Now we have to make the mold for the actuator’s base layer. This is simply a rectangle that has the same dimensions as the main actuator, with a 4mm raised lip around the edge.

Measuring our actuator (Evaluate > Measure) gives us the dimensions 112mm x 15mm.

Extrude a 112mm x 15mm rectangle to 3mm thickness. Use the same method as before, with the alignment lip, to create a 4mm high lip around this mold.

The completed base mold should look like this:

Save it as a .stl file.

The mold solid models are now complete. You can use the .stl files you have created to make the molds with a 3D printer.
