Prints

You can use the 3MF file to print an entire set, it contains:

• 1x - BootConnector

• 2x - SpurConnector

• 1x - Spur

Assembly

• Flex the SpurConnectors onto the outside of the BootConnector

• Cut off a small section of filament from the spool

• Stick that filament through the hole in one SpurConnector

• Then through the hole on the Spur

• Then through the hole on the other SpurConnector

• With PETG, you should be able to bend the ends of the filament to "lock" the spur into place.

• If you want to be extra-secure, some hot-glue or super-glue would work fine, just make sure not to glue the spur, you want it to spin freely.

Print Settings

• Support: None

  • Each part prints with the flat side on the bed

  • No overhangs

• Filament:

  • BootConnector: PETG

    • You want that slight flex that PETG gives you

  • SpurConnector: PETG

    • You'll be flexing this part over the BootConnector

  • Spur: PETG/PLA/Whatever

    • This part is just to be pretty, use whatever you fancy.

• Perimeters: 2

• Infill: Doesn't matter, nearly every model here will be 99% perimeters.
