This is a STL file to 3D print an adjustable card spacer I designed to keep cards from sliding around in CCG/TCG card storage boxes that are not filled. It can go from about 2.5 inches to 5 inches. There is an easy thumb wheel that can be spun while in the box to adjust for a snug fit or opened to search thru the cards.
You are allowed to print off as many as you wish for personal use but this is not a commercial license. You may not print to sell.`
