Clamp for Isosan (Praktiker) toilet flush accessories

thingiverse

These outdated toilet flush systems are constructed of brittle plastic, which fails miserably after two decades, causing the plastic nipples to shatter into a million pieces. To replace the entire system, you're forced to rip open the surrounding wall, what a nightmare! Luckily, I've found an easy solution by using these clever clamps that can fix the problem in no time.
