My Toliet Flush button broke, so I printed a new one in ABS, Acetone Vapour Bathed (to SEAL it) and will paint the next version over with Nail Varnish.

Print at a high fill - to prevent internal holes where germs can breed.

Print in ABS then ACETONE VAPOUR BATH to completely seal.

THIS WAS A 1:1 REPRODUCTION OF THE ORIGINAL BUTTON - Simplified for 3D Printing. I've since seen this isn't the best, and have designed a prouder, taller button for cistern flushes and put it here:

Enjoy.
