Rubber Grip Molds
thingiverse
A 3D printable mold that fits around 1/2" PVC, fill it with silicone or whatever other material you want, and clamp it around the pipe. Insert screws and tighten nuts to close mold and squeeze out excess material. Dimensions should be 2.75" wide by 5.5" long and 1.25" tall for the female side (side B) and 1.5" tall for the male side with the nubs (side A) The holes for the screws should be .2" diameter, but I had to drill mine out a bit to fit the screws. I will link my instructables tutorial for this as soon as I finish it. Required hardware: x6 #10-24 screws, 3 1/2" long x6 #10-24 wingnuts x12 #10 washers
