Self-Filling Paint Roller with Built-in Reservoir

Hey, Makers! I'm excited to share with you my latest practical model that will surely come in handy around the house!

Self-Filling Paint Roller with Built-in Reservoir

This universal paint roller holder allows you to fill the roller itself with paint. It's designed to fit standard paint rollers with an inner diameter of 44mm and widths ranging from 145mm to 230mm.

How it Works

The design converts a standard replaceable paint roller into an airtight paint reservoir. To allow the roller to wet its painting surface, you'll need to create holes in it. To simplify this process, I've developed a specialized tool (instructions and video guide provided below). Using this tool along with a regular nail and hammer, you'll easily create the necessary number of holes with the appropriate diameter.

Hole Quantity & Diameter Recommendations

For reference, I used a 180mm-wide roller and relatively thin paint. To achieve even coverage, I created around 30 holes with a diameter of approximately 3mm (using a 3.1x70mm nail). If you're using thicker paint or wood varnish, I recommend making larger-diameter holes.

Assembly Instructions

Below, you'll find a video demonstrating how to assemble the holder and install the roller.

IMPORTANT: To ensure an airtight seal, wrap sealing tape around the parts inserted into the roller.
