adhesive dispenser plunger 3d model

"A professional technical 3D model of a black 50ml 10:1 ratio dual-component adhesive plunger rod, based on image_0.png. Total length: 185mm. The head features two parallel pistons: a large 21.5mm diameter piston and a small 6.8mm diameter piston, with a center-to-center distance of 14.8mm. The shaft has a reinforced U-profile body made of matte black industrial polymer. At the rear, there is a 16mm teardrop-shaped finger hole. Crucially, the underside of the shaft features high-precision Buttress (sawtooth) threads with a 1.5mm pitch and 1.1mm depth, designed for a mechanical manual dispenser gun. The design includes structural ribbing for high-pressure resistance. Industrial studio lighting on a gray technical grid mat, showcasing the matte texture and precise engineering dimensions. Sharp focus on the 10:1 volumetric ratio geometry and thread details."
