<p>This is an upgraded version of this:<br/> <a href="https://www.thingiverse.com/thing:3519669/files">https://www.thingiverse.com/thing:3519669/files</a></p> <p>modified to make it easier to print , assemble and disassemble.</p> <p>The z axis rods are mounted a little looser for easier assembly, but can be clamped in place with two M3x10 bolts and two M3 square nuts.</p> <p>The bearings are a bit looser too. If they are too loose, wrap them in electrical tape.</p> <p>The design has been modified to use an Openbuilds anti-backlash block instead of the regular leadscrew nut. A printable version of the block can be found here:<br/> <a href="https://www.prusaprinters.org/prints/56496-openbuilds-anti-backlash-nut-block-printable-versi">https://www.prusaprinters.org/prints/56496-openbuilds-anti-backlash-nut-block-printable-versi</a></p> <p>Source here: <a href="https://github.com/MatejPavel/3D-model-source/blob/main/3018%20CNC/Z%20axis%20upgrade/source.7z">https://github.com/MatejPavel/3D-model-source/blob/main/3018%20CNC/Z%20axis%20upgrade/source.7z</a></p> <h3>Print instructions</h3><p>0.4mm nozzle<br/> 0.2mm layer height<br/> 3 perimeters<br/> supports off</p> <p>Bigger nozzles could probably work too, but the holes would need to be drilled out.</p>
