<p>A handle for a 6.3 mm Hex Shaft. Intended to assist with nozzle changes.</p> <p>Design considerations:</p> <ul> <li>Accept a standard 6.3 mm Hex Shaft.</li> <li>Use M3 bolts and nuts to secure shaft (likely in spares from printer build and mainenence).</li> <li>Large enough for some grip.</li> <li>Small enough to avoid over tightening a nozzle.</li> <li>Not too tight, not too loose.</li> </ul> <p>Heat from a hot nozzle will transfer to the handle.</p> <p>I advise Annealing PLA if you choose to print in PLA (my personal choice). PETG may well be ok with the heat, PC almost certainly ok with the heat. I have not tested all possible combinations.</p> <p>Designed with FreeCAD.</p> <p>2021Jan08: Added holes to assist with removing hex driver or nut.<br/> 2021Jan16: Added a low profile version (lp) for hex shafts with scalloped profiles. In the low profile picture we can see the difference a correctly levelled bed (after moving the printer) makes to the print: black before levelling, orange after.</p> <h3>Print instructions</h3><ul> <li>Prints without supports</li> <li>Check the gcode files for the correct nozzle size and material for your use.</li> <li>Post-processing for PLA: Anneal to avoid deformation or melting in use. I suggest scaling the print by: X and Y 102% and Z 98% if annealing. For annealing HTPLA I am use X and Y 101% and Z 99%.</li> </ul>
