No.

Most of the diagram is right. Every part sits on one centre axis, in the
right top-to-bottom order: knob, lid, plunger rod, filter, retaining nut,
glass beaker, frame. The knob is above the lid, so it threads onto the rod
after the rod passes through the lid's bore. The lid's pour notch lines up
with the beaker's spout. The beaker drops into the frame.

The error is the 3-piece filter, which is drawn upside down. The diagram
shows, from the top: cross plate (4), mesh screen (5), spiral plate (6),
then the nut (7).

In a real plunger (the Bodum-style design shown here) the order from the
rod end is: spiral plate, then mesh screen, then cross plate, then the nut.
The spiral plate carries the spring coil that seals against the glass, and
it sits on top. The mesh is sandwiched under it. The cross plate is the
bottom piece, and the nut tightens against it. That is what squeezes the
mesh up against the spiral plate.

The diagram's own label for part 4 says it "clamps screen to spiral plate".
That only works if the cross plate is on the side opposite the spiral
plate, next to the nut. As drawn, the cross plate sits on top with nothing
to press it down, and the nut bears straight on the spiral plate. So the
cross plate clamps nothing.

Fix: reverse parts 4 and 6, giving spiral plate, mesh, cross plate, nut,
from top to bottom.
