Parametric Jar with lid

I created this small parametric jar with an elegant ribbed outer surface and a smooth inner surface and lid. Ideal for storing small items or for use in the kitchen. Creating a couple of different size jars with different colored lids can create a playful effect in your kitchen. The size of the jar can be changed in 2 ways:By changing the height: the standard height is set to 100 mm. This is the height of the jar only! So excluding the lid. The minimal height is 40 mm and the maximum height is 159 mm. The diameter of the jar is not affected by changing the height. By changing the scaling factor: the standard scaling factor is 1. With this setting, the height is exactly as entered (e.g. 100 mm). By changing the scaling factor, both the height and width are affected! In this way, you can create smaller or larger jars. The minimal scaling factor is 0.4 and the maximum scaling factor is 2; I've done it in this way to make sure the wall thickness stays constant and create a nice rib pat
