My wife's cookie press cap broke after first use. I tried to model something as close to the original as I could. There are two variants...one with the nubs on the outside and one without. I haven't printed the one with the nubs yet, but the plain one prints just fine.

Prints without supports! Threads real nice (for me, anyway). Hopefully this will come in handy for someone else :)

variable because of threads

I sliced in PrusaSlicer and used variable layer heights to help the threads print cleaner. Most of the model printed at .2mm, while the area with the threads printed closer to .08mm. Took about 2.5 hours to print.

Prints upright without supports. There is an expendible bridging layer that will need to be cut out once print finishes. It's super easy to clean up with a razor knife.

PLEASE REMEMBER: PLA prints are't exactly food safe. Reusability of this may be limited for hygienic reasons. Good thing you can print a bunch of them!
