Disposable (the one on the cover photo used less than 3g of material) filter for filtering used resins before storing them.
This is supposed to be printed on a standard FDM printer.

• Must be sliced with 0 bottom and 0 top solid layers!
• Use Rectilinear infill. By varying the infill density you vary filter's fineness.
• Parameter wall thickness should be set so the walls slice to one thick perimeter.
  This will depend on your extrusion width and slicing engine.

When you are done with this or actually any filter, cure its resin remnants with UV before throwing it away!
