A handle for a 6.3 mm Hex Shaft. Intended to assist with nozzle changes.
Design considerations:
- Accept a standard 6.3 mm Hex Shaft.
- Use M3 bolts and nuts to secure shaft (likely in spares from printer build and mainenence).
- Large enough for some grip.
- Small enough to avoid over tightening a nozzle.
- Not too tight, not too loose.
Heat from a hot nozzle will transfer to the handle.
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.
Designed with FreeCAD.
2021Jan08: Added holes to assist with removing hex driver or nut.
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.
Print instructions
- Prints without supports
- Check the gcode files for the correct nozzle size and material for your use.
- 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%.
