Take back total control of your mobility—and never worry about a missing knob again. Factory-standard joystick knobs are often made of thin rubber that wears down, gets sticky, or simply doesn't fit the unique needs of every hand.
At Lynch 3D, we’ve engineered a range of high-performance, 3D-printed joystick toppers designed for durability and ergonomic relief. Every order includes four (4) identical knobs, so you always have a fresh spare or a backup for travel and second chairs.
(All styles come as a 4-piece set)
The Standard: A clean, no-nonsense replacement for the original factory knob. Features a solid-core build and a textured top for a more secure "thumb-and-finger" grip.
The Mushroom: Our most versatile hybrid. The wide, flared cap supports the palm while the tapered neck allows for precise "pinch" control. Perfect for all-day comfort.
The Golf Ball (Large Sphere): Designed for maximum surface area. The iconic dimpled texture provides high-friction grip points—ideal for users with reduced hand strength.
The T-Grip (Horizontal Bar): Engineered for maximum leverage. The wide bar allows you to drive using your palm or the side of your hand, shifting the work from your fingers to your arm.
The 4-Pack Value: You receive four matching knobs per order. Perfect for backups, spares, or multiple chairs.
Industrial Durability: Printed using high-density, automotive-grade polymers that won’t crack or peel like cheap rubber.
Precision Fit: Each knob is custom-bored for a secure, "no-wobble" friction fit on standard joystick shafts.
Made to Order: Need a specific color or height? As a 3D-printing specialist, we can customize your 4-pack to meet your exact needs.
Quantity: 4 Knobs per order.
Compatibility: Fits most major brands (Permobil, Pride, Quantum, Invacare, etc.).
Standard Shaft Size: 1/4" (6.4mm) — 3/16" (4.8mm) available upon request.
Install: Simple press-fit; no tools or adhesives required.
