About this 3D model

The Prusa Mini is an awesome machine, but the clever way they built the Z-axis carriage makes checking the extruder quite difficult. I have designed this mod to transfer the motion of the extruder gear on an outside cog that can be seen from the front of the machine. There might be the need to break in the gears on the screws to make them roll smoothly. It requires 2 M3x16 screws. video here!
