8mm lead screw knob for MPCNC

prusaprinters

<p>This is a beefy lead screw knob I designed for my MPCNC primo, though I'm sure it might be useful for other things.</p><p>You might need to drill out the center hole to get it to fit the lead screw. I used an 11/32 drill and it worked perfectly. Something like xy compensation in the slicer might help dial it in too - or your print might have the right sized hole right off the printer.</p><p>You will need two 5mm square nuts and two m5x16 socket cap bolts.</p>
