If the STL file describes an object that is larger than the maximum dimensions your printer can produce, you can print the object in two or more pieces and glue them together. There are times when we want to make some adjustments to them to better fit our need or 3D printing equipment. There are also some online tools to convert STL to STP online, although they have less versatility and performance, it’s worth a shot if you have no access to PC software.There are many free STL files are available on the internet to 3D print useful objects at home. If you’re interested in other common file conversions for CAM, check out How to Convert Gerber Files into G-code using FlatCAM.
