A functional pneumatic plunger to unclog a sink.

How to use:

  • Screw-in the rod into the cylinder.
  • Install the pneumatic cylinder. We want a very tight fit, it will settle after a few movements. Use some candle wax around the cylinder to push it inside. Start with the standard cylinder: CYLINDER 0.0 (standard size). Print only this cylinder first.
  • If it's too tight, print CYLINDER -0.2; it’s a cylinder with 0.2 mm smaller diameter.
  • If that doesn't work, go to CYLINDER -0.3.
  • If the standard cylinder doesn’t fit tightly for some reason, try CYLINDER +0.2 or CYLINDER +0.3.
  • Use an optional skirt for a better suction in some sinks.

Printed at 0.1 mm layer, 20% fill. Supports: NONE. 0.2 mm layer should be OK.

We use PLA - no need for any waterproof material, the pump is submerged and operates for a short period of time, so any material should be OK.

What material is it printed in? Can TPU be used for the skirt and plunger head and ABS for the rest?
