Parametric Rift DK2 IPD adjuster +/- 4mm

This is parametric version of my IPD adjuster for Rift DK2 that allows you to generate adapters with IPD from 59.5 to 67.5 that use B Lanses and requires a slight modification of the lens housing (see Instructions, pictures).
I was in home sick and decided to learn OpenSCAD and this is what came out of it.
[EDIT]
I wanted to be cool and make this model customizable from the website but it looks like is a bit too complicated causing the Customizer to time out (don't know why - if anyone know how to fix this let me know). Sorry but you'll have to download it and run it in OpenSCAD (or similar software) yourself :(
