A Addition to the Threads

[PabloJonesUK]

Just an idea that would be useful would be the add options for Most standard plastic lemonade bottles that use a 28 mm PCO 1881 thread, and cap . as in the Image below . and one for gallon container, like a Screen wash , or bleach container , and finally standard a washing up liquid bottle , threads and caps ,

@PabloJonesUK thanks for the idea! The next version has a new series in the thread size menu, "PCO – Bottles", with PCO 1881, the 28 mm neck of most water and soda bottles (27.4 mm, pitch 2.7). It brings its flat thread profile along, so you just choose the size: make the neck as a threaded rod and the cap as a nut, or subtract a tapped hole from a cylinder. The measures come from the standard's drawing, so please print a small test piece first and let me know how it fits a real bottle.

For the gallon containers and washing-up liquid bottles there's no common standard, each maker uses its own neck. For those, measure the neck you have and enter the diameter and pitch under "Custom size".

@PabloJonesUK PCO 1881 is out now in layerling 1.128.0: you find it in the thread's size menu under "PCO – Bottles", with its flat profile. https://github.com/henmedia/layerling/releases/tag/v1.128.0

I'm struggling to find PCFO - Bottles in v1.138.0,

I just thought of another standard thread size. People use preserving jars, (Mason Jar), regular or wide mouth for many things. Mason, Kerr, Ball brands. I've seen sippy cup lids that the replaces the standard flat top and the threaded ring fits over. or pour spouts for syrup, or water bottle tops, or soap dispenser.
I created a container using a bolt that I placed a hollow cylinder in the center and then created a nut with a very short threaded rod in one end to close the nut to create a cap. Using a thread to close-off the end of the nut leaves a circle on the outside instead of a smooth cap.
It would be nicer to create a bottle cap for 2 liter bottle or beer screw top or wine screw top.

@Oldandretired it's in there: select the thread, open the Size menu in its panel and scroll down to the last group, "PCO – Bottles". PCO 1881 is also the neck of 2 liter soda bottles, so for a cap choose that size with the role Nut or Threaded hole.

For a cap with a smooth top you don't need to close the nut with a rod. Make a cylinder a few millimetres taller than the thread, put a Threaded hole in PCO 1881 into it from below, shorter than the cylinder, and group the two. The hole then stops inside and the top stays closed and smooth.

Thanks for the idea of jar threads like Mason and Ball, regular and wide mouth. It stays here as a suggestion for now.
