Customizable bead cylinders are available in various forms, as shown in the photo, which offers multiple ways to create them in any quantity, size, or shape - including a simple cylinder form. Initially intended as a test, I was about to delete the file until I decided to share it to save time for designing and to determine the type of design you're looking for. Hopefully, this will be suitable for your needs and provide many possibilities to consider.
