About this model

V2 Coming soon! V2 will be compatible with the newer U-shaped front bracket & Y plate hole pattern(s) The original design placed the belt too close to the frame which caused severe belt misalignment. This could be due to my unit being an early model, poor QC or a number of other reasons, so I moved the holes for the belt retainer blocks out 4.6mm. I figured I wasn't alone in my endeavor to fix a wobbly bed, so I wanted to make this remix available. A HUGE shoutout goes out to the original user for doing most of the heavy lifting on this design. Don't forget to degrease your rail & carriage. Pre-lube everything if you want to do it now or save the mess & wait until its mounted. BOM * 1 x Ender-3 * 1 x 300mm MGN12H linear rail * 2 x M4x20mm screws * 2 x M4 t-nuts * 2 x M4 washers * 4 x M3x25…
