This set of file handles for chainsaws allows you to sharpen with two hands, either by pulling or pushing, depending on the direction of the file. The handles can be printed at full speed and can have different shapes on each end, for example square and flat handles, which are relative terms used for easy identification only. Furthermore, the product includes a knob and a twist grip, both of which can be printed together with the handles. Need oil for your chainsaw bar?
