I was greatly inspired by the original thing: https://www.thingiverse.com/thing:5982704

I did my best to recreate it (as close as I could guess) entirely in OpenSCAD. Use the customizer to create your own size, or download the scad file to fidget with the code yourself!

Also included is an optional threaded ring in case you wanted to add an accent color. This adds about 2mm to the total height.

The interior diameter (23mm) and exterior diameter (35mm) are similar to the original.

The inside height = total height - 4mm.

UPDATE 2023-05-15: I have updated the SCAD file so that RIDONCULUS MODE is enabled!! The maximum height is now 192mm. Use caution, as I have no idea what that might to to the rendering time at that height. That might be big enough for pencils now.

UPDATE 2023-06-29: New version of this thing includes the ability to change both the diameter and height. https://www.thingiverse.com/thing:6061562
