Printrbot Simple Metal Upgrades

These are parts and a base design to support a bunch of upgrades to the Printrbot Simple Metal. I have more detail on each of the upgrades on my web site **[here](http://www.slipjig.org/#/posts/printrbot-simple-metal-of-doom)**.

Here is a list of all the upgrades:

- **Wooden 'Throne' Base**
- Duet 2 Maestro
- Wifi Module
- **BLTouch Z Probe**
- Improved Heated Bed
- Improved Print Surface(s)
- Replacement Bearings
- Stepper Dampers
- Upgraded Fans
- Z Lead Screw Stabilizer
- Flexible Z Coupler
- Power Switch
- **Filament Runout Sensor**

Items in bold have associated files posted here.

NOTE: the BLTouch mount is sized for an Ubis 13S hotend. With that hotend and a BLTouch 3.1, the probe when mounted should be ~60 mm below the mounting hole above, in its retracted configuration. You will probably want to measure to get the desired distance with your hotend in mind, and scale the part in the axis accordingly before printing.
