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.
2014/6/15 update:
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
    • 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.

Thanks for this customizable design. Very useful indeed. I used it to create a model for bathroom sinks (thing 2641316)

A few minor suggestions/requests:

  1. Add in the parameter comments hints how to have no handle. (I used 0.01 height but you can have a condition for handle height=0)

  2. Add in the parameter comments hints how to avoid side slots. (playing with the top/bottom margin?s)

  3. Allow to increase $fn. At least for the three large radiuses. The default one is a little bit rough.

  4. change the specification of side and bottom slots from ration to mm. This will allow to easily set it to the max object diameter you want to let through.

thank you this is so useful for many things !

I downloaded it, modified it to fit our sink and works great. Thanks for the design.


Simple, effective, elegant, useful. Customizeable and openscad source included. True spirit of the community. Well done, A+

Added: As far as Nicklaus's comment, I disagree, but don't want to get into a whole thing, and take away from this fine product that you obviously put so much time into. But I will say:

  1. I could print a ten years worth of this product, and it would probably use less resources than what it takes to: make a sink strainer in steel, deliver it to Walmart, and I purchase it with money I had to earn. Disposable does not mean that it is not greener. Please figure materials, wheels, distribution, delivery, and attainment resources before making a claim of such.
  2. I printed mine in biodegradable PLA, using energy from my solar cells on my roof. Fully sustainable and green.
  3. I could have this printed in a long term material, even brass at shapeways, and it would still be greener, as well as not be disposable if that is your issue.
  4. I think you might need to look at what opensource actually is. There is no opensource purpose that "it be greener." I don't think Junnno "forgot the purpose of these types of opensource projects," the purpose of the item is this: Share a way to drain a sink.
  5. Can't a person just make a thing and share it, without it having to have controversy. Can't we get a break from all these silly small steps that have little to no effect on the real problems of the sustainability of the earth and sometimes just relax, print a thing, have fun.

Don't fall for the virtue signaling bait.


Too late.
In fact, 3 years to late, lol...

That's what the '2014' means. I see.

Thank you for the time and effort to design such a complete customizable object. This is one of the cleverest openscad items I have seen.

I have made strainers for all my sinks!!
This is the type of customizer that would make a great demonstration for the way that you can use a 3d printer for common everyday items. THIS SHOULD BE FEATURED!

Disposable sounds so lazy and bad for the environment. I think you forgot the real purposes of these kind of opensource projects. How about printing a reusable item or just using a drain strainer for its purpose which is emptying the material collected in it. I was interested in printing this but only just because of your title and info that I didn't. Cheers!

This think is customizable. You can easily create a version that is reusable to fit your needs.
