3D model description

Due to the surprising success of my portafilter spout that just doesn't splash or sputter I've been asked to adapt this design to another espresso maker:The Lelit Anita. Since the thread is a "standard" 3/8" screw it's supposed to fit other models too.

Material-wise I recommend some high-temp food-grade plastic such as Colorfabb HT. Here I used ONE PET filament because I've already had good long-term experience on this exact application. There's a chance of nasty stuff to leach out at 100°C, but I don't think that will happen on a relevant level since the contact time for espresso is very short. Otherwise you'd be doing it wrong and that extra plasticizer serves you right.

(I haven't tested this design since I don't own this espresso machine, but the user - who also sent me the pictures - says it fits like a glove. Or a mitten. Whatever.)
