After a while the original Techzone Huxley X carriage with a single bronze bushing started to get sticky, despite of any oil I fed it. It created some massive backlash on the X axis, so I designed this :Used to replace the original single bronze bushing X axis carriage with 3 LM6UU linear bearings.Includes holes for mounting a better attached hotend (with a peek block retaining the nozzle).Parts needed :Based on PRUSA Mendel X-carriage by Josef PrůšaThe Openscad file, along with any dependencies needed, is in the zip archive. UPDATE Added ziptie holes to secure the linear bearings.1) Print.2) Fit the 2 belt attaching M3 bolts that goes under the LM6UU (might need to use the soldering iron to push those in).3) Snap LM6UUs in - you might want to secure them using zip-ties so they don't move - I had to open holes with my dremel for that. Feel free to add holes to the design :)4) Dismantle your X axis5) Remount your X axis, replacing the 6.56mm non metric rods with 6mm ones and the old X carriage with this new one.
