Grohe faucet repair

thingiverse

I'm planning to replace the failed water limiting button on my old Grohe faucet, which has been around for 18 years, since a tiny part inside the knob snapped off. To fix this problem, I've created a ring using Openscad that fits snugly inside the broken knob. The design should be easy enough to modify so you can adjust it according to your faucet's unique features. This is version 2 of the design; the first one had a few problems with parts breaking off on the second level because they were situated right at the middle of a 0.2mm layer. However, I've managed to correct this by making sure that all subsequent levels start exactly where a multiple of 0.2mm layer can be printed cleanly. If you decide to print using a different layer height, then you may need to fine-tune the settings in the Openscad file accordingly.
