Lift. Pop. Dump. Repeat.

The original Pop Open Drain Strainer was a game changer — and now it's even better.
Introducing Drainer – Version 2.0, the upgraded print-in-place sink strainer designed for durability, improved performance, and one-handed ease. Trap food scraps while keeping your hands clean, and empty it with a single press.

I have included two versions.  The two have different strainer designs in the floor (bottom) of the Drainer.  Please see the included image.  A few people have indicated that the original hex bottom design works better for some foods.

**Key Features:**

- One-press pop-open trap door for mess-free emptying
- New integrated lift handle keeps the strainer securely closed during lifting
- Raised interior ribs help food scraps release more easily
- Improved drainage grid lets water flow while catching the mess
- Thicker wall sections for extra strength and longer life
- Print-in-place hinge + support system – no assembly required

This version is optimized for ABS, which resists hot sink water better than PLA or PETG. It includes built-in support for the trap mechanism that break free during post-print setup.

**Post-Printing Setup:**
After printing:
Gently defuse the built-in hinge supports by prying apart the marked faces.
Press and rotate the Drainer to release the trap.
Remove the temporary print support (shown in orange in diagrams).
You're ready to strain and dump like a pro.

**Dimensions**
Outer Diameter: 3-1/4" (83mm)
Height: 1-1/4" (31 mm)
Designed to fit most standard kitchen sink drains

**Notes:**
This is a single-piece, support-integrated model – no hardware, no adhesives.
For best results and heat resistance, print in ABS.
Designed for strength and long-term daily use in the kitchen.
Compatible with common sink openings; check fit before use if your drain is non-standard.

20250815: I have added a second version to this download, which includes the original hex bottom design.  

20250907: I have uploaded a new version of the hex bottom design which corrects two issues with it.   

20251004: I have uploaded new versions of both models.  The new versions have improved geometry that will make them print better with less overhang.  And, I have removed some of the print support to help them open up after printing more easily.  I have added an instructional video as well on how to open them after printing.
