Grout Sand Roller — Joint Packer Tool

A 3D-printable roller tool designed for pressing polymeric jointing sand (such as Gator Sand) firmly into paving joints, ensuring a compact and even fill. Description This tool consists of two parts: a fork adapter that clamps onto a stick or handle, and a rolling disc that spins freely on a bolt between the two fork arms. As you roll it along the joint, the disc presses the sand down evenly without scattering it. The disc is designed so that only the outer 30mm edge enters the joint, while the reinforced center hub keeps it rigid under pressure. Parts included fork_adapter.stl — Clamp-style fork that slides over a 27.5mm diameter stick/handle. Features a slot for a clamping screw, two rounded arms, a square recess on one side for the bolt head, and a round through-hole on the other side for the bolt shaft. disc.stl — 100mm diameter rolling disc with a 5mm center hole, 3mm flat outer edge (30mm wide) and a reinforced center hub.
