Improve the ergonomics of your shovel, rake, or any other garden/yard tool by adding a 2nd handle. This version is designed for tool handles that are an inch or slightly larger in diameter - up to 30 mm. It is designed for use with ¼" nuts and bolts.
Print with lots of walls and top/bottom layers for strength - my profile has 8 walls and 10 top/bottom layers. Infill really doesn't matter but I used 15% gyroid.
Other sizes coming - add a comment and let me know what size you need.
