Download Free 3D Model Plague Doctor Syringe 3D Print Model

Summary
What to print:
You need the “Body-Ring” three times. Every other part is only needed once.
How to assemble:

Glue 2 of the 3 body-rings onto the “handle-holder” part.
The remaining ring is glued onto the “plunger-cap”

Screw the handle-holder and the fluid onto the body. Both go in thread first.

Put the Body-Ring onto the fluid.

Screw the needleside-cap and the needle onto the fluid.

Pull the plungerside-cap over the plunger, thread first.

Screw the plunger into the plunger-cap

Push the plunger-assembly into the syringe and screw it onto the handle-holder.
Et voilà
You could print the Body and Body-Ring as one object, if you used support material.
