This could be used for blanking any 19mm hole. For me it is for blanking a hole drilled in the wrong place while attempting to fit a drawer lock. If you ave a different sized hole and cant be bothered working out the scaling just ask.I used PLA, 10% fill, 2 shells, no support needed. The flat part is very thin,so it fits snug against the front of the drawer.For this reason allow it to fully cool before you remove it. I have added one with a thicker face ( 1mm ) because when I printed in white PLA it was slightly translucent and the darkness from the inside of the drawer showed through, of course it wont be quite as flush.
