Customizable Temperature Tower for Slic3r

___Attention:
I recommend anyone to use the newer version of this model here: https://www.thingiverse.com/thing:2615842 !___

This is practically a remix of kmsd's "Customizable Better Temperature Tower" ("https://www.thingiverse.com/thing:2491884). The main difference is that you can change the direction of where the highest and the lowest temperature will print: on top or on the bottom of the tower.

I also have made a __second version__ of this remix with an __overhang__ on the right side with a __pointy cone__ on top of it. This is supposed to show how exact your printer prints (and cools) small pointy details. See https://www.thingiverse.com/thing:2615842 for version 2.

### Usage example in Slic3r:
- - -

#### 1. Generate the tower with openscad:
$ openscad tempTower.scad
Set the following variables in the openscad window to your liking:

// temperature of the first lowest block
start_temp = 220;
// temperature of the last highest block
