Customizable smart temperature tower + injector script

This is a customizable temperature tower based on [Thing:2729076](https://www.thingiverse.com/thing:2729076).
I included a Python script to easily inject the temperature steps into the .gcode file.

##**Customizer Parameters**

- **start** - the initial temperature
- **end** - the temperature of the last block
- **step** - the temperature step between blocks


##**Steps**

1. **Open 'customizable_tower.scad'** in OpenSCAD and **change the parameters** to suitable values. (The Customizer can be opened under Window -> Customizer). Then, **export an .stl file**.
**Alternative:** Use the Customizer on Thingiverse.

2. **Slice the .stl file** with your preferred slicer.

3. **Run the included python script** to inject the temperature steps.
Usage:
```
python temp_injector.py input_file output_file initial_temp temp_step [section_height] [base_height]
```
Example:
```
python temp_injector.py tower.gcode tower.injected.gcode 225 -7
```
Help:
```
python temp_inject
