I made these mounted trash bag bins specifically for the Red/Green waste bags used in my region of Sweden, but you may find them useful for your own situations as well! I have mine mounted on the cabinet drawer under my kitchen sink for super convenient and accessible composting.

The design consists of four parts:
- A lid
- An inner rim that connects to the lid
- An outer rim that holds the trash bag and snaps onto the wall mount
- A beefy wall mount that securely clips onto the rim.

Default print settings should work out. I used PC filament to make the mount extremely resiliant but I suspect most filaments should be sufficient. The rest of my parts were printed with PLA. Share your results if you try something else!

The mount has holes for up to 6 wood screws, but I only used the top 4 and it's enough, even with short 19mm screws. The holes are sized for threads up to 4mm wide, but you should be able to expand the holes by pre-drilling if necessary.

**_July 18, 2025 Updates_**
- The lid and inner rim used to be a single print in place part, but this has proven to be unecessary. The parts are now split and you can flex the inner rim to snap the lid onto the hinge.
- Added a new **locking** lid! This upgraded lid snaps into the open position to stay up on its own.
- Looser version of the locking lid is also included. Useful for thicker trashbags or less precise printers.
- **note:** You **must** use the Locking Inner Rim together with the Locking Lid.
- **note:** The new Locking Inner rim requires **support material** generation turned on! It's a small amount of supports, but this enables the flap on the lid for easier handling.
