optimal parametric drain lid

With 3D-printed lids it is always the “it will never fit my glas” thing. So if your glas ist not 4 threaded and 65mm in Diameter (including threads). 

Just use the oSCAD script measure your old Lids inside put this in “d=” and count the threads (normally 4 or 6) “sym=”. Render(F6) save and print. 

For smaller sprouts you can also change the hole size.
