This ergonomic butterfly valve handle slips directly over standard manual “butterfly” valve knobs (common on radiators, towel warmers, and plumbing systems) to give you better grip and leverage—no tools needed!
✅ Fits standard ½" radiator valves
✅ Internal dimensions:
– Central hub diameter: 24 mm
– Total width (tip to tip of wings): 53 mm
✅ Easy snap-on installation—no screws or adhesives
✅ Pro tip: Print with a textured or rough outer shell (e.g., using “fuzzy skin” in Cura or similar settings) to prevent slipping—especially useful with wet or cold hands!
✅ Comfortable, tool-free operation—great for elderly users or tight spaces
✅ Optimized for 3D printing (no supports needed, minimal overhangs)
Print it in PLA, PETG, or ABS—PETG recommended for durability and heat resistance near radiators.
Note: Always check your valve dimensions before printing. This design fits the common “butterfly” knob with a 24 mm central disc and 53 mm total wingspan.
