Intake Strainer for Fluval Canister Filters

The small intake strainer was clogged frequently with debris, this part fits over to pre-filter. 

Our Fluval canister filter (406? I think) had an intake strainer with an OD of ~28mm.  This strainer was designed with a tapered ID for a simple press on fit.

3mm or #4-40 screws hold the top and bottom parts together.  I used 12mm long screws, but anything longer than 6mm should be fine.
