These 3D printed drum spacers were made to work with Ludwig drums that use the "mini" Classic lugs. Compatible Models: Ludwig tom and bass drums that use mini classic lugs. These were modeled after the spacers found on modern classic drums, but will technically fit vintage mini classic lugs as well. Material: TPU Note: All items are 3D-printed and will have the surface finish of a 3D printed item. There could be some variations or inconsistencies in the 3D-printed finishes. However, we strive to print the highest-quality items! Also, the pictures of the color options shown in the listing are of full-sized classic lugs and are just for color reference. If you have any questions or requests, feel free to reach out. I have a pricing structure for custom work as well if needed.
