How do I assemble a sliding block?

 Please note: this process is the same for Ultimaker 2 and Ultimaker 3 series printers, but be aware that the Ultimaker 2Go and Ultimaker 3/Ultimaker 3 Extended belts are not interchangeable with the Ultimaker 2 belts, as they are different sizes. The Ultimaker 2, Ultimaker 2+, Ultimaker 2 Extended, and Ultimaker 2 Extended+ all use the same size belts. No tools are needed for this process.

Two assemble a sliding block, you'll need these five components:

• 2 block halves (they are identical)
• 1 belt
• 1 spring
• 1 bushing

Follow the video guide below. For installing your finished block in a printer, please see this article on replacing parts on the X and Y axis.
