Drain cover / hair catch for bathtub and bathroom sink. Customize with customizer or just edit the openscad file and change the scale at the top. I included the stl's for a 38 mm (bath tub drain) and 28.5 (bathroom sink drain) Hmmm.. Accidentally included s3g instead of stl =/I printed this at .2 mm layer height with 100% infill to make it strong. It will print without support, but looks nicer with it. I used replicatorG so that I could remove the support material.
