About this 3D model

2.0- modified version with more structural support. Open doors without touching round knobs with your hands. This is a simple design and quick fix for typical architectural door knobs. Use a tiewrap to tighten on doorknob. There are two models. S- for knobs under 2" diameter / M - for knobs over 2" diameter. Mirrored versions are included for use depending on which side of the door the knob is located. We recommend 100% infill for print settings. Feel free to download, modify and make recommendations. We are working on a 3.0 version that does not need tie-wraps. Parallel to this we are working on a pull version too.
