This modular design gets you back in business fast. Print the base knob (small or big size), then just print whichever D-shape tip matches your appliance's shaft (6mm, 7mm, or 8mm) — no measuring guesswork, no waiting for a proprietary part to ship. Each tip snaps into the same 12mm socket, so you can mix and match without redesigning anything. Fully parametric, budget-printer friendly (no tight tolerances needed), and printable in under an hour with zero supports required. Two knob body sizes, 3 tips to adapt the D-shape, and a hole for a toothpick in the button to dislodge the tip.
