Addon for Geberit - WC tablet holder https://www.thingiverse.com/thing:4942867

The WC tablet holder holds a cleaning tab that turns the toilet flushing water blue. It is designed for Geberit toilet systems and rimfree toilets.

I bought some cheap tabs at LIDL. I noticed the tab was fully emerged and dissolved within a week. I created this insert, which goes into the holder upside down to rise the tab out of the water partially. I hope the tab dissolves slower this way.

If you need it to be higher or lower, resize it in Cura by changing the Z-axis to the desired height (uncheck "uniform scaling" so X and Y are unaffected).

Print with closed side down, no supports. Insert into holder with closed side up.

As seen on the pictures, always stay around the printer to look at how the first layer is going. I didn't look at it this time, and it came out a bit messy.
