Model paint opener (Customizable)

Inspired by https://www.thingiverse.com/thing:1656200 this is a generator that can be modified to fit various sizes of paint bottles, and probably also a lot of other stuff.

Update 2016-09-10:

• Fix the grip border size (was half of intended).
• Fix the handle hole border size (was half of intended).
• Better generate resolution.
• More smooth handle.

Maybe it would be nice for some to have a list of settings value to set, that fits various different lids. The default values is set to fit the sizes of the inspired tool. If you make a print that fits some other paint bottle, feel free to send a message with the config values, so that others can make it as well.

Update 2016-09-14:

• Updated the default size to fit Tamiya Paint Mini.
• Added test boolean to print only the grip to test size.
• After several tests, found the ideal size for Tamiya Paint mini to be diameter=37.7

Update 2016-09-15:

• Fixed how to set the test "boolean" so that it works with the customizer app. There is no support for booleans, so now it is a string.

I would advice people to create a test print, setting test="true"; and setting the height=2; to not wast plastic, when testing for the right grip size.
