Hollow cylinder for filament holder made with a stand

thingiverse

Create a filament spooling solution with a retort stand and an OpenScad-defined hollow cylinder. Utilize a retort stand, featuring two vertical bars (ideally 1.2m), a horizontal bar (1m), and connectors to secure the horizontal bar. The OpenScad module defines a hollow cylinder with parameters for outside diameter, inside diameter, and length, designed for filament spooling. Customize the size of the filament roll hole to accommodate various sizes commonly found in the market. Print the cylinder using any 3D printer, preferably with moderate fill, and in PLA due to its ease of printing, low friction, and smooth surface. Ensure that the first two layers are printed slowly for a round cylinder. Adding clamps can enhance stability during long print sessions. This setup has been used successfully for over five years, providing easy-to-turn filament reels during unsupervised 24-hour prints.
