Filalab spool spacer (for Gravity spool holder)

Spacer for Filalab spools.

Had hard time tightening and loosing gravity spool holder nuts with Filalab spools due their spool shape. This little spacer helps a lot. (See pictures for difference)

Spacer sits nicely to spool and stays on during storage, but can be removed, if you don't want to print one for every spool.

There is two versions of this, since the design of spool has changed.
See images for reference.

• FilalabSpacer_v2.1 is for newer spools made 2021 and after (note: spool, not filament. See spool for manufacturing time dial)
• FilalabSpacerOlderSpool_v1.1 is for older spools. These spools have thicker spokes (2.5mm)

Example part is printed with these settings, with Filalab Black PLA

• 0.6mm nozzle
• 0.35mm layers (0.2mm first)
• 2 walls, 3 top and bottom layers
• 10% infill, rectilinear
• 215/60*C

Part doesn't need to be super strong, so you can use fast and “ugly” settings.

Updates:

• OlderSpool_v1.1 and Spacer_v2.1 have simplified geometry. They should also print a bit faster.
