This is an adapter for the Quest 2 controller. It uses the original SANLAKI holder for the controller and a bigger handle for pickleball. After printing I gripped it with my normal tennis grips. 

Handle should be printed upright and the top piece needs a bit of support. I used some Velcro to keep the controller in place. The pieces click into each other and don't need superglue, although it is recommended. 

15% infill works well for best realistic weight ratio, but you might want more on the holder piece for strength.
