Made this to fit my 1.5 inch tub drain and use less material over some of the other designs I saw. Cura shows 6 grams which is roughly a 50% savings after resizing the other ones down to fit.
Much easier to resize to fit your drain as the widest point is the critical dimension. I found that ~2mm of clearance was enough (it fit but was still easily removable) so keep this in mind if you need to resize. Manually adjust the height to fit your drain but mine had 1inch of depth so as is this model stick up just above that for easy removal.
No supports needed
Probably don't use regular PLA due to lower temperature resistance.
