Filament Cradle

Filament cradle, 2 required for each spool, takes around 30 mins each and about 30g of filament. Because you don't go through the centre of the spool you can seal the spool and let it just sit on top. Self tapper thread, just drill a pilot hole to get it going. Flat spot of the spindle to allow you to use a spanner if you need to tightened it more than just with your hand.
