Anti-Backlash nut mounter/adapter - TR8

thingiverse

This is an adapter/mountblock designed to mount an Anti-backlash nut onto an Ultimaker 2 printbed instead of the notorious Chinese brass nuts. I have created a YouTube video showcasing the difference between the standard brass nut and this adapter + backlash nut. The adapter can be used wherever brass nuts are employed, provided space constraints permit. A border has been incorporated to help keep the Anti-Backlash Nut centered. To see an Autodesk 3D model, which you can download in various file formats, go here. I utilized Autodesk Fusion 360 to develop this model. There is a standard STL download available here on Thingiverse as usual: Print Settings: Printer: JennyPrinter Rafts: No Supports: No Resolution: 0.25mm Infill: 70% Notes: I employed 3 perimeters using a 0.4mm nozzle. It is recommended to use a resolution/layerheight that can be divided by 4 and 5 without decimals. High infill should be used for strength, as you do not want this part to wobble. Post-Printing: Insert M3 nuts into cut-outs: Simply insert two M3 nuts into the bottom of the piece. If necessary, use glue to keep them in place. Attach the adapter to the printbed or other surface: Next, attach the Anti-Backlash nut onto the adapter using two M3 nuts. Important: Ensure the Anti-Backlash nut is centered. To achieve this, do not lay the printer on its side, as the bearings on the 12mm rods may shift slightly. Take it slow! Mount the adapter and verify it is centered by mounting the motor and leadscrew, then run the bed up and down a few times. Repeat this process after attaching the Anti-Backlash nut. Just insert two M3 nuts into the bottom of the piece. Find four fitting screws with round heads. Loosely mount the Anti-backlash nut before tightening it down when you are certain it is centered. Custom Section: Why I used M3 screws instead of M4? To conserve space and make the item stronger, as well as because it's uncommon to have such short M4 screws available. Custom Section: You need to cut material away from the Anti-Backlash nut. If you use the bed-cover for Ultimaker 2, you must remove some of the base of the Anti-Backlash nut. You can utilize this adapter as a guide for cutting. I strongly advise using a pillow-block to secure your lead-screw in place before employing this adapter!
