Here is the rewritten text: Hello everyone, I'd like to share a new project that's easy to set up and print, just like you can see in this fact. We use two steel cushions of type 608 ZZ, which are very common in the market and also used in our rollers or skateboards. They're easy to find too! We also use a bar of iron or a screw with a length of 140mm and a diameter of 8mm. A pair of nuts with an outer diameter of 13mm and an inner diameter of 8mm are also included, so you can easily replace your old roller with a new one that's more efficient. Have fun!
