LM8UU Carriage for Overlord / Overlord Pro

thingiverse

No more need to make M3 threads, as now the carriage has slots for M3 locking nuts. Material reduction is estimated at ~45%. The first experimental designs of a new carriage for the DreamMaker Overlord 3D printer use LM8UU type bearings (8 mm linear ball bearings). This design is still in progress and requires much more work to be completed. If you want to print experimental parts, take apart your Overlord, have LM8UU bearings on hand, and are ready to get frustrated, feel free to give it a try in its current form - but wait until the real bearings arrive for better testing first. You will need to create M3 threads in the carriage as well as remove the built-in support material. Make sure you turn off support in your slicer! The goal of using LM8UU linear ball bearings is to decrease the noise created by original bronze bushings when sliding along 8 mm shafts; the shafts are ground incorrectly (perpendicular to motion and not parallel like they should be). Original bearings needed constant lubrication or they'd get extremely loud during motion. The design will change to a 3-bearing system with a built-in belt tension system.
