Table Tennis Low Serve Trainer

thingiverse

My WCTTA table tennis coach emphasized that effective serves should clear the net by just 20mm (the ball's radius). To practice this, you can use these stands and a broomstick, which blocks any serve higher than 20mm. However, note that the stands are over 6 inches long, so they won't work on small 3D printers. I printed mine on a Replicator 2 with two shells and 10% infill. For the broomstick, use one measuring 5 feet and 7/8 inch in diameter. To secure the stands between your table tennis table halves, attach furniture felt protectors to their base (or substitute with taped or glued cardboard squares if needed).
