Print Instructions

This model includes multiple tolerance options to ensure the best fit for your specific printer and filament.

• Start with the “Normal” version.
• If the blocks feel too loose, try the “Tighter” version.

• there is also an “Extra Tight” version

Different printers and filaments can affect clearances, so you may need to experiment slightly for the perfect spin and click.
