Englefield Shower Drain Cap

Common Englefield shower drain cap as found in Australia and New Zealand, possibly other countries. Have made it stronger than original and it fits well. Printed in ABS or ASA 0.16 and vapor-smoother with acetone in a rice-cooker. Has stood up to 6 months use no problem at all in our family bathroom.The original part is expensive and hard to source! Top is flat, not convex, print top down for surface finish and slight grip.No supports needed.
