2-Part DN100 Rainwater Pipe Filter: Coarse + Fine
Print Profile(1)

Description
Inspired by the filtration concept used in dishwasher filters, this two-part filter insert is designed for DN100 (100mm) rainwater downpipes.
The coarse filter on top blocks leaves and larger debris, ensuring that coarse dirt and foliage do not clog the fine filter.
The lower basket filters everything larger than approx. 3–4 mm.

The coarse filter snaps into place in one defined orientation only, preventing incorrect assembly and ensuring consistent flow.

I personally use this filter on the downpipe of my garage roof to keep the rainwater system clean and prevent blockages.
Ideal for rainwater tanks, cisterns, roof drains, and downpipes.
IMPORTANT: Printed with Extrudr PETG. If you use a different filament, adjust your print settings accordingly.
