Chopstick coupler & ball for target training wand

Target training wands may not be expensive but they aren't cheap either. I have been thinking about ways to make one for even less. All you need is a 3D printer, some superglue, and takeout chopsticks. Instead of paying $10+ USD or more you can make something that will work for less than $0.50.

The dimensions of chopsticks tend to vary so I made the openings for the couplers a little oversized. You may need to pack some tissue paper in the hole with the glue for a tighter fit. The opening on the sphere is a little tight so if it doesn't fit your chopstick tip you might have to increase the scale before printing. Round hole opening on the coupler is supposed to be 6mm. The rectangle hole opening on the coupler is supposed to be 7.5mm by 5.5mm.

I included my straight couplers and offset coupler design since I already designed them and they both worked. The normal straight couplers are the better design.
