I have a very small dishwasher, so I designed this Dishwasher Tab Splitter to break the tabs in half. Just put the tab in, press the guillotine part in (with some force) and wait for a small clicking sound - the tab breaks in the middle.
Note: The tabs I'm using have a length of around 37mm, a width of about 27mm and a height of ca. 15mm. This splitter might not work for other sizes. I'm also not sure if the effectiveness is brand-dependent...
I added more versions of the guillotine part:
Note: You can, of course, always scale the model in one direction to fit your needs.
