Parametric Modular Cup Holder & Handle

The first model is an open cup-holder ring with adjustable diameter, wall thickness, front horn gap, optional rounded tips, bottom support, bottom slot, and a true round side socket for attaching a hook or handle. The second model is a rod-style handle/frame made from rounded capsule elements. Each part of the U-frame and L-section can be adjusted separately, including length, diameter, inner gap, overlap, and optional hook geometry. Both models are intended for customization, testing, and modular 3D printed holder systems.
