Shower Drain Catch and Plug

Onshape and Parametric model can be found here: https://cad.onshape.com/documents/1286cb920ace9e97703932d9/w/f8e0da6c347404eea4820bfb/e/82046ff02b6d474e4a4d2bd1?renderMode=0&uiState=681fe8620a36d0374f69d6c7 These models fit my particular drains exactly with a rubber gromet between the plug and the catch. My main drain is 43mm diameter and has 33mm until the part at the bottom. The other drain has no holder and uses the smaller model, but most dimensions are parametric on the Onshape and can be adjusted to match your drain. Just size around 1-2mm in on the top from measured and slope in at the bottom.
