After designing my original pop-open drain strainer about a year ago, I knew I would eventually need to create a second generation of it. I knew there was a better design out there, I just couldn’t think of what it was until now. This one is so much better…
The original design had several problems, but the most significant was that there was no handle. And, even after I added a knob to it for lifting, it did not seem right because the knob did not help you open the Drainer. But the new design (posted here) solves that and so much more.
It is stronger and more durable, has improved drainage, better retention when closed, and raised ribs that encourage food scraps to slide off better.
The new handle is also part of the opening and closing system. When you lift the Drainer up using the handle, you are keeping it closed, which is important if it is full of food scraps as you swing around to your garage receptacle. Then you rotate your fingers slightly so that you can press the pressure point with your thumb, causing it to pop open, while at the same time holding the handle to suspend the Drainer. It might sound complicated but it feels very natural once you have done it a few times.
It prints as a single piece with one piece of support to be removed after printing. And, I recommend printing it in ABS if you can, as it has a higher Tg (glass temperature) than PLA and PETG, making it better able to survive the hot water typically found flowing into sinks.
Print Settings
Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.
This product was designed for a 0.4mm nozzle, a 0.2mm layer height. For best results I suggest the following:
Assembly Notes
There is no assembly required, but you do need to carefully defuse the print before using it and remove the built-in print support.
