Ping Pong Arm Replacement
by jkeegan, published
About a year ago at a party, a coworker heard about 3D printing for the first time and asked me if it would be able to print a replacement for the broken arm of his ping pong table (which holds up the net). I said of course it could do that, and then procrastinated for over a year getting around to designing and printing it for him.
At first I was just going to print an L shape with the holes in the right place, but I eventually decided I might as well model it to closely match the original.

Print with the cylindrical arm on the bottom and the base sticking up in the air. When the print is done, break off the two round support pads (and the small rectangles connected to them).
Screw an M3x25 screw into the bottom of the base until the head and a few mm of the bolt is all that's visible. Use whatever mounting screws your old ping pong arm used to mount it to the table, on the other side of the base (see pics for side-by-side comparison with the broken original).
As I understand it the end of the net has a string that goes through the circular notch at the end of the half cylinder, then down the outside of the cylinder, then loops around the M3 bolt.
