This Wrist Correction Aid looks to improve the consistency of your swing by correcting the position of the golf club in your backswing. Proper clubface alignment is key to consistent on-plane swings, and this tool is perfect for guiding your wrists to being in the right place.

This model prints in 3 simple pieces and assembles without any glue or hardware. Simply slide them together and get swinging! I've made sure to include two different models - one for standard grips and one for midsize grips. Minimal supports are required, but they are very easily removed. Model can be printed in PLA or PETG. All parts have been oriented for optimal strength, so material is not as much of a concern.

There are similar products all over, with YouTube tutorials showing how to practice with trainers like this. Simply line up the trainer parallel to the leading edge grooves of your clubface, and swing away. Your goal should be to place your leading hand's wrist into the cup of the correction aid.
