weight plate 3d model

A realistic gym barbell weight plate outer shell designed for 3D printing. The model is hollow inside with thin walls (about 3–5 mm thickness). One side of the plate is completely open so the inside cavity is visible and can be filled later. The outside looks like a standard round weight plate with embossed weight numbers and grip cutouts. Center hole for Olympic barbell (50 mm). Clean hard surface, mechanical design, optimized for 3D printing, manifold geometry, no internal supports, high detail, STL style.
