Remix of Post Cap by 3dprintingworld #OutdoorThangs Additional model used https://www.printables.com/model/166307-tennis-ball/files Remixed the top to allow a screw in topper attachment. There is also a channel for water to escape the hole if a topper is left off.A Tennis ball in this case. A perfect edition to your deck for your Tennis fanatic. 4 sizes available: 75mm (3 in), 100mm (4 in), 125mm (5 in), and 150mm (6 in). This is the size of the ball not the overall size including the screw. The screw adds 10mm to the Z height. Printed with .2mm layers and fuzzy skin to give it that Tennis ball look and feel. Support are needed for the ball topper, just the bottom. For the ball topper I suggest 3 walls and 10 % infill if using a .4mm nozzle. Make the top and bottom to match the wall thickness too. Picture has the 75mm ball.
