I designed this in Tinkercad for a neighbor, who is a baker. He asked me to try print one of these that he cannot find anywhere as a replacement/backup part.
I’m having troubles with the threads. Basically the supports printed ruin the threads and it’s very difficult to remove.
Another problem is that the top triangles break off very easily. Any advice either on the model or print settings to modify?
I’m using Wimbo PETG @ 0.2mm, 230 Deg extruder, 90 Deg Bed, 30mm/s
Hmm. I’d go so far as to make the threads inner circumference wider (whilst keeping the threads outer circumference the same), then switching down to 0.1mm layer height so you don’t need supports.
For the top triangles, I’d make the outer wider so that they’re thicker. There’s no reason why they can’t be from a functional point of view, and that should give them more strength.
Those top triangles are gonna be tough. At that point, reduce the speed a lot, and turn the fan all the way up.
I’ll try both suggestions and let you know how it goes.
Keep in mind that producing a food safe nozzle is very difficult: https://all3dp.com/1/food-safe-3d-printing-abs-pla-food-safe-filament/
Hmm. 230 seems a bit low for PETG. I usually print at 260. Makes it a lot stronger.
I’ll give it a try
