About this 3D model
You are about to download an .stl file of a model so you can build a D handle for your training. For assembly you will need a round wood stick. I made two versions, 1st for wood stick with 1 Inch diameter and 2nd with 20mm and 35 mm holes. I designed this together with a push up bar during the COVID19 lockdown, when it wasn't possible to visit the gym and I needed to exercise at home. Works great :)
