Here is a 3D printer Paddle by KC5ILR mounted a piece of solid brass 3x3x.500 which makes it plenty heavy even for the hardest slappers. These paddles perform as well as any paddle I even owned, and I have owned many very expensive top end paddles. I even sold my Schurr Profi after playing with these paddles. The brass cost almost as much as the paddle. Paddle comes with two adjustment wrenches. Will Take BEST OFFER over $40 ----Shipped Anywhere PayPal preferred. Reply to email@example.com only please.
