The file 'Height Adjustable Router Support For Rotary Tool 3D Printer Model' is (stl) file type, size is 3.5MB.
This gadget converts your rotary tool (i.e. Dremel) to a handy router. The inner thread of this gadget is compatible with most Dremel-like tools. The height can be adjusted by turning the knob part. The thread pitch of the adjustable mechanism is 2 mm so each half a turn lifts the tool 1 mm. Total movement of the lift is around 20 mm depending the machine is used. I've tested the gadget with Bosch GRO 10,8 v.
