Full-Size Trash Bag Wall Holder

Most trash bag holders are either too bulky, too weak, or only designed for small bags. This one is different.

The Full-Size Trash Bag Wall Holder is a compact wall-mounted solution designed to hold a large household trash bag securely while taking up almost no floor space. It is perfect for garages, laundry rooms, workshops, storage rooms, kitchens, cabins, utility spaces, 3D-printing areas, or anywhere you need a real trash bag without a full bin standing in the way.

The main idea is simple: the bag is clamped evenly between the green frame and the black locking bars, then tightened with the blue knobs. This keeps the bag open, stable, and properly held in place without slipping down like many simple hooks or loose bag holders.

Unlike many existing solutions, this is designed for full-size trash bags — not just small grocery bags or lightweight desk waste bags. It gives you the function of a large trash bin, but in a much cleaner and more space-efficient wall-mounted format.

Why this is useful

Traditional trash bins take up floor space, are awkward to clean around, and are often bigger than needed. Simple bag hooks save space, but usually do a poor job of keeping the bag open and secure. This design solves both problems by giving the bag a solid frame and a proper clamping mechanism.

The open frame also makes it easy to see when the bag is full, remove it quickly, and replace it without fighting with a bin liner.

Design notes

The frame uses a lightweight geometric structure to keep the design strong without making it unnecessarily bulky. The bag is held between the front locking bars and the main frame, with the knobs tightening everything in place.

This is especially useful because there are not many full-size trash bag holder solutions like this on MakerWorld right now. Most designs are either small bag holders, simple hooks, or bulky bin-style prints. This model is meant to fill that gap: a practical, printable, household-size trash bag holder that actually holds the bag properly.

Installation

Pictures and video shows assembly of the two sides.

Mount one of the sides first securely to the wall using suitable screws for your wall type. The click in the second side and screw it in as well. 

Insert the bag between the frame and the locking bars, then tighten the knobs until the bag is held evenly at the corners.

Do not overload the bag beyond what your wall mounting and material choice can safely handle.
