Degassing whip for wine

cults3d

A simple de-gassing wand for home-brew wine; print several and thread onto an 8mm stainless or chromed smooth rod at least 20cm long (better 30-40cm though). A demijohn can use 2-6 but for a 20+ litre fermenter, use maybe 10-12. Print solid in a decent quality flexible filament - if you use a rigid or even very stiff plastic, the tines won't bend through the neck of a demijohn, and you'd have to use an antimicrobial silicone sealant to attach the tines to the rod. With a flexible, they should be quite difficult to get on and grip the metal very snugly as you don't them come loose when withdrawing the whip through a demi's neck! Print one to start and make sure it's a really tight fit on the rod. If it's not, shrink the print by 5% in the slicer or e.g. Tinkercad, and try again. Repeat until it's almost impossible to get the whip onto the rod. In the pic I have the whips all up against each other, but I have since spaced them out a bit to make it easier for the starsan solution to properly sanitise every nook and cranny.
