ANY FURTHER UPDATES WILL BE ON PRINTABLES: https://www.printables.com/model/170496

Store cylinders (cans, etc.) on their sides and be able to pull them out easily with them rolling around. These shelves fit the cylinder and stack so you can build up multiple levels. Put a label on the end of the cylinder if you want to know what it is.

Each shelf only contacts the cylinder in a centimeter at the front and a centimeter at the back, to save filament. They also stack! Fill out the customizer with the diameter of the cylinder and how far apart you want them to be.

For each cylinder you want to store, print two ends and two rails. For each level you want to stack the shelves, print four supports as well.

This is parametric - you can use the Thingiverse customizer if a miracle has happened and it's working, but it's better to download OpenSCAD at https://openscad.org/downloads.html and open the shelves.scad file in it. You don't have to write any code to use the customizer in OpenSCAD! The customizer will appear on the right side of the screen; expand the Basic tab to fit the shelves to your cans, expand the Advanced tab to change other options around fit and size. Export an STL of the end, support, and rails and print as normal from there.
