just another round object holder

I use this holder to hold a screen opener.
It is fully customizable if you use openScad.
The customizer does not work. I think it has two problems: I use a library file.
I also use the "angle" option in openScad for the rotate_extrude. This only works on the 2016.xx versions of openScad. So please download the newest version.

You can set:
- number of clips on one strip
- distance between clips on strip
- inner diameter of the clip
- wallthickness of the clip and strip
- adding screwholes
- width of a clip
- angle of the opening. 0 = fully closed. 180 half open etc.

The rcube.scad library is a simple library to create cubes with 4 or 12 rounded edges.
