You will need to print:

• 1 main body
• 2 side bevel gears
• 2 middle bevel gears
• 2 pins
• 2 side gears

Instructions:

• Pick side bevel gears. You will know which they are as only these fit tightly on bigger side gears.
• Locate larger holes on the main body (pins would fall out of these).
• Place side bevel gear inside main body on this bigger hole and press fit it with bigger side gear.
• Repeat with second bevel gear on opposite side.
• This step is a little bit tricky. Hold side gears so they can't spin and place middle gears on opposite sides of each other. Slide them in simultaneously and check if holes line up. If they don't repeat this step.
• If you were successful press pins in securing the gears.
• Enjoy
