This model is designed to hold an exacto knife, some people call them hobby knives, or scalpels. Whatever it is, its handy to clean up prints and supports so this model keeps it nearby the workstation. The orifice for the tool holder is 10.5mm diameter, and is set on 30* angle for ease of access without tipping. It has a space for a spare blades case, as well as an empty slot for used blades.

Happy Printing!
