ORAC Lathe Spindle Stepper Mount

As I'm upgrading [my ORAC lathe](http://www.wolfteck.com/orac/), one function I want to play around with is precision spindle control. This mount holds a [NEMA 23 stepper](https://www.amazon.com/gp/product/B00PNEPI0A/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=wolfteck-20&linkId=273dd46eefbe804989f8d7b9e8fb3ec4) inside the headstock. The stepper is connected to the spindle via my [ORAC Spindle Pulley](https://www.thingiverse.com/thing:2813937), [ORAC Spindle Stepper Pulley](https://www.thingiverse.com/thing:2813941), and a [320-2GT](https://www.amazon.com/gp/product/B00PNEPI0A/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=wolfteck-20&linkId=273dd46eefbe804989f8d7b9e8fb3ec4) timing belt.

The bolt posts are designed to be printed as plated without supports.
