Hello, I present to you my first project carried out on fusion 360.

To install it you will need 8 diameter 3 screws (the length will be determined according to the thickness of the wood of your heavy duty shelf).

As well as two steel tubes with a diameter of 25mm (approximately 1 inch).

I suggest you reinforce the place where you will install the supports, because the steel tubes are heavy, so are the spools.

Let me know if there is any problem with my creation, I will be happy to help you and resolve this problem.
