This smart and simple jig from iBookbinding, allows you to have perfect 90-degree angles when making boxes - every time! A Metal screw provides enough tension so that the clamp will not slip and will hold the corner properly while the glue dries. An opening at the tip of the corner allows you to check if pieces of cardboard are connected perfectly. To apply even more pressure, the movable part has a special thumb holder. And rails will guarantee that the angle is always perfectly straight! The Clamps are based on the original design by Marcelo Castillo. They are 3D-printed and set at 90 degrees. Available in 2 sizes: Small - 30mm long - 9mm wall height Large - 55mm long - 15mm wall height The Clamps are based on the Original Design by Marcelo Castillo.
