Knob - small - #8-32 and M4-.70

prusaprinters

<p>These smale knobs are identical except that one is sized for a #8-32 screw and the other for an M4-.70 screw. Use the appropriate tap to thread the center hole after printing.</p> <p>To use, simply screw in the proper sized screw (I use round head screws) and tighten (don't over-tighten or you will strip the plastic threads). You can add a drop of thread-locker (or CA glue) if you like, but I have not found this to be necessary; also, I like to be able to dis-assemble on occasion.</p> <p>The OnShape 3D CAD files for this can be found here:</p> <p><a href="https://cad.onshape.com/documents/d23c6a795d512aba8d13715b/w/09014aff2faddd7421f0a8f1/e/3a10f9e97815bfff35392c41">https://cad.onshape.com/documents/d23c6a795d512aba8d13715b/w/09014aff2faddd7421f0a8f1/e/3a10f9e97815bfff35392c41</a></p> <h3>Print instructions</h3><p>Use the .3mf files provided; otherwise:</p> <p>infill = 20% rectilinear<br/> top/bottom fill = concentric<br/> perimeters = 4</p>
