Tennis Racket Vibration Dampener (using a pencil-end eraser)

thingiverse

Hasn't seen any useful thing really about tennis on Thingiverse yet. So I decided to create one. This is a dampener for tennis rackets/racquets. It nearly didn't cost me anything. "FIX" includes one piece with a position fixer and a flat piece (You'll see what I mean) with my initial. "NORMAL" includes two flat pieces (one with my initial on). "DE-INITIALED" includes one flat piece without my initial. (Knew you guys wouldn't like my initial on it... ) See material list and instructions on the instruction page Instructions BOM: You'll need: M3 or1/8" nut and screw of 10mm or 3/8" (the best choice) or longer(1) The printed parts. you'll need two flat pieces (NORMAL) or one flat and one fixer (FIX) Super glue or any other kind of glue that could hold rubber and plastic together (optional but highly highly recommended) A rubber from a random old wooden pencil or any rubber cylinder that has diameter that's around 7mm (between 5/16" and 1/4") (use a piece longer than 5mm at least) (I used the rubber form a papermate mechanic pencil. ) A utility knife (I used a swiss army knife. scissors might work), and an allen wrench for your screw Instructions: prepare your stuff. cut the rubber into 4 pieces that are about 1mm thick or thicker. the thicker the more dampening the dampener will be (I guess...but not too thick of course) glue the rubber pieces to the round hollow areas of each piece of the printed parts. (you could pass this step. but then it would be really maddening later) screw it on the racket. hope you do know where on the racket. (if not see my picture.)
