Printed variable size Y Carriage

thingiverse

The default model of complete carriage uses outdated sizes that are still in use today. However, you can create a variable-length or weight carriage if desired. There are two possible variants: ### 3 x LMU8 with middle part This is the original usage found in Prusa printers, which features three LMU8 bearings. In this setup, a middle part is required and plugged into one side between the two corners. ### 4 x LMU8 Some printers use a carriage with four LMU8 bearings, two on each side. Without the middle part, you will need to secure the corners using two nuts. ### Additional components needed * Two 146mm M6 threaded rods * Two 215mm M6 threaded rods * Eighteen M6 Nuts, or twenty if not using the middle part * Three M3 x 20 bolts * Two M3 x 15 bolts * Five M3 nuts * Stripping tapes to secure bearings If longer rods are used, a longer or wider carriage can be completed for larger beds.
