This model was created to make the arm that holds the soldering iron a lot more rigid. The design is the same as the stock roller plate except I added the t-slot protrusion from the weight holder to the back of the roller plate. This design makes it a lot sturdier and saves you the 18 USD that you would have to spend on a cheap linear rail to get the same sturdiness, but more smoothness. A flaw in this design is it rides very close to the extrusion causing it to feel very rough as the gantry moves up and down were as a linear rail would make this movement feel smooth, however over time it will smoothen out. Supports are built into the design and should be very easy to remove once done printing. If y'all have any questions or like to report an issue please leave a comment. Thank you all and I hope this helps you out.
