Thank you! i will give this a shot. looks like i'll have to get a few new plugins!

Hey there, I'm currently trying ti simply recreate a simple shampoo bottle that i have and I'm nearly done! i have done all of the volumetric measurements and math PLUS the modeling for the bottle, but I'm stuck on the threading to affix a pump at the top! i saw a few tutorials on youtube about how to make threading for a screw or a bolt, but i don't think i can achieve the same result using that method. maybe I'm wrong who knows! anyways id love any feed back on this.

Thank you guys for your time in advance.
