This is a Gridfinity 2x1 box, 35mm high, that holds nippers a scraper and a few smaller tools (like pens or cutters).
I originally printed the one designed by @Neven3D, but I received a plastic razor blade scraper as a gift (not a sponsored link), which did not fit the holder, so I had to make a wider space for it. At the same time, I was not using one of the spaces, so I decided to redesign it to fit other smaller tools I needed.
The author remixed this model.
Wider scraper space, and new spaces for smaller tools.
