Window holder

This is a remix of parts 3 and 5 from [capitaenz's window holder](https://www.thingiverse.com/thing:235732).

Part 3 and 5 have been merged together. The original part 3 was designed to be stuck in front of the window, but this one is meant to be stuck on its edge.

So, in order to print what you see on the pictures, you need to download this remix and capitaenz's parts 1 and 2.

You easily can make adjustments in SketchUp Make with the given `.skp` source file.
