About this 3D model

I did this design a while back and only posted it now because I finally found a god place for it. You got multiple ways to grip it from easy round ones to very thin ones and even a slope. I screwed mine to a wooden board (I made some fittings inside the part that exactly hold some nuts to reenvorce the fit), which is screwed to the wall. You want at least 2 cm distance from the grip to the wall, else you can‘t grip around the top! Feel free to leave your feedback in the comments and post photos of your final part, I highly appreciated that.
