<p>Companion piece to my other remixed z-axis wheel knob Thing: <a href="https://www.thingiverse.com/thing:4663397">https://www.thingiverse.com/thing:4663397</a></p> <p>As before: I threaded R2 dome to an extruder's wheel knob. I wanted them to be separate parts and removable, so you can change the head to anything (or just leave it off).</p> <p>Reason for two rod screw files: I used the 8mm 100% size to cut the holes out of the wheel and dome. But the printed rod I had trouble screwing in to the objects, so I made one that's 90% of the X/Y, and only 14mm tall so there's less of a gap when screwed together. Feel free to use the 8mm file to cut your own holes to put other models on top.</p> <p>If you're having trouble getting perfect circles, tighten your X and/or Y belts. If you're still having trouble fitting the parts, you can scale the XY of the rod screw and it'll fit, though may be more loose.</p> <p>Extruder wheel knob by techboner: <a href="https://www.thingiverse.com/thing:3176144/">https://www.thingiverse.com/thing:3176144/</a></p> <p>Rod screw by mike_mattala (apologies, couldn't add this Thing to the "Remix Source Files" section for some reason): <a href="https://www.thingiverse.com/thing:193647">https://www.thingiverse.com/thing:193647</a></p> <p>R2D2 by 3dscratchbuild (I only used the dome, but it's a full R2-D2!
