3D printing "Ultimate frame"

"There are three options for the original frame: 'Printed verticals,' '2040 upgrade,' and 'Ultimate frame.' With each performance improvement, there is an increase in aluminum extrusions and threading. I'm not very interested in achieving extreme performance, but using the 'Printed verticals' version alone causes deformation even when moving it (due to the rear vertical frame causing uneven force distribution, with the front rods unable to provide stability when lifting). Therefore, I designed a 3D-printed front frame in the style of 'Printed verticals.' I'm not sure if this design improves printing performance, but it significantly enhances stability during transport and makes maintenance on the upper frame much easier." You can loosen the front Z-axis rods and slightly move them down, allowing for maintenance and modifications while keeping the upper frame securely fixed—just like this: 📷 Image redacted — claim this model to add your own media I moved the connection points of the front vertical frame up a bit, allowing more printers to print all parts in a single run. Other than that, it is consistent with the 3D-printed rear frame, so you can directly refer to the rear frame during assembly.
