This is a holder for mini interdental brushes of brand GUM, but could possibly be compatible with other brands. In the files, you will find a FITTEST.STL, to see if it is compatible with your brand: it will only print one position. If you just want to test the size of the hole and not the complete length, just stop the print midway with a color change code M600 and stop.
The brush holder is separate from the storage box.
The brush holder has no bottom.
It fits in front of the storage box and forms a nice bathroom kit with it's sleek design.
