What is Gridfinity Refinery?

Gridfinity Refinery is a free browser tool that makes Gridfinity bins and baseplates from a form, with no CAD needed. It sends your settings to the gridfinity-rebuilt-openscad library by Kenneth Hodson on its own server, shows a 3D preview in the browser and lets you download the part as STL or 3MF.

On the Bins tab you set width, depth and height in grid units, turn the stacking lip on or off and add magnet or screw holes, crush ribs, scoops and label tabs. Dragging across a small layout grid splits the bin into compartments, and a paint mode lets you draw L-shaped or other odd pockets. Compartments can also get cylinder, slot or hex cutouts or a sloped floor, and two optional CadQuery renderers round off the sharp inside corners.

The Baseplate tab offers thin, weighted, skeletonized and screw-together plates. Enter your drawer size and it pads the edges to fill the gap, then cuts the plate into pieces that fit your print bed and gives you a ZIP of STLs. Layouts can be saved to a file and opened again later. It suits people who want more control than a basic bin maker but still want to work from a form. It is a newer, smaller project than the best-known Gridfinity generators.

Small project with little community discussion
