I tired to clean up the strainer of the kitchen sink every week, then I designed a disposable strainer printable.
I choose OpenSCAD because it is highly parametric design.
And fortunately, it made the design customizable to fit your sinks.
I found that the knob for picking up was essential after use. So I added it referring http://www.thingiverse.com/thing:85416 .
Set handle_height = 0 and handle_lower_diameter = 0 if no center knob is needed.
Print and put it on the strainer flange.
I made the prototype sample using the below condition.
- Hardware: Replicator 2X
- Material: ABS
- Software: MakerWare 220.127.116.11
- Resolution: Low (Faster)
- Build plate temperature: 115 deg.C
- Raft: Off
- Supports: Off
When I made it from PLA, biodegradablity was not a problem at least several month in use, but PLA was soften by very hot water. It is highly recommended for you to keep using the original strainer under this one for fault tolerance.
