Toaster 25 is another unique burr puzzle from the creative mind of Alfons Eyckmans. This nine piece burr behaves more like a board burr, but the component boards have a three-dimensional "thickness". This "thickness" is added in the form of a variety of protrusions that allow more interaction with adjacent pieces, thus creating a more difficult puzzle.
There are four ways to assemble this puzzle according to burrtools. All are mirror assemblies, surprisingly all are level-25 but the total moves vary from 41 to 44.
Toaster 25 is based off of Toaster 16
