CORNERO Free 3D print model

The purpose of this connector design was to create a rack for my growing collection of 3D printing filament. Often, filament spools are stored by their center, hanging on horizontal rods; that’s a quick and fine idea, unless you need the middle spool…! So I created this four-point connector, designed for using ½” aluminum tubing to build a rack of any length. This connector has a removable, contoured cap for a finished look in a single-level configuration, and to allow adding vertical tubes when removed, for creating additional levels, as shown in the rendering.

Each connector is 4½” tall (with the cap…), and 1¼” across at the widest, and the center is hollow, for materials economy. The tubing sockets have a stop ridge inside, at ½” deep, to provide consistent depth for tube sizing. The examples were made in light grey PLA on an UpMini and guaranteed printable, just as shown. So far, I’ve only built the small rack in the pictures, using ½” aluminum tubing. For this setup, the depth rails are 5.75” long, and the horizontal rails are 10.25” long; it holds three spools.

Although I haven’t tried this, with different spacing, this could also be a CD/DVD rack, or anything you can imagine.
