Modern Fluted Trash Bin (with Liner-Locking Ring)

About This Project

In my journey of learning FreeCAD, I wanted to design my first custom trash bin, keeping the multi-material capabilities of my Creator 5 in mind. The design features a sleek, fluted exterior and includes a small, custom-fit inner ring to hold your trash bag perfectly in place. The ring is intentionally designed with a slight tolerance to allow for a bit of flex. Simply place the bag inside the ring, fold it over the top, and press the assembly into the bin to pinch and lock the bag securely.

The version shown in the image was printed as a multi-material project without a prime tower! Instead of wasting filament on a tower, I enabled the Print Infill First setting. After running a few successful test prints with primitive shapes, I took the gamble on the full model, and it paid off beautifully. To elevate the look even further, I applied a fuzzy skin modifier strictly to the top rim to give it a premium, fabric-like textured effect.

Print Settings & Filament Specs

This is designed to be a premium, sturdy piece of room decor. At these settings, it uses about 602g of filament. While that might be more than your average economy utility bin, the result is a solid, high-quality piece that looks fantastic and won't feel like a flimsy piece of cheap plastic.

Layer Height: 0.24mm
Walls: 2 wall loops
Infill: 10% (I highly recommend 3D Honeycomb, but use your preference!)
Prime Tower: None (Enabled Print Infill First and the Wall Printing Order set to Inner/Outer for clean tool-changes)
Textures: Fuzzy skin painted onto the outer collar/rim for a textured finish.
Time: Using these settings on the Creator 5 took 12 hours to complete. This may be longer on an AMS machine.

If there is demand for it, I can cut up the bin into two pieces: the main body and a separated top ring that can be glued into place. Leave a comment and let me know what you think!
