This is part of an upcoming vinyl cleaning machine with a vacuum, but is useful on its own when cleaning records by hand. Has a pause at the 30 layer mark to drop in a ¼ nut. Also you can print a second one, and skip the nut and drop in a ¼ bolt after printing so they match up. Also buy https://www.amazon.com/dp/B00C3YDIZA?psc=1&ref=ppx_yo2ov_dt_b_product_details and hot glue to create a seal for record.
