CUSH - Custom Spool Holder

This is a customizable, simplified OpenSCAD based clone of TUSH - The Ultimate Spool Holder. So first of all thanks to filamentry for his innovative design.

This spool holder shares all the features of TUSH that are important to me, it is simple to print and can be assembled without the needs of any tools or parts (like screws) except for the 608 bearings. It looks less _fancy_ (curvy) than TUSH but it can easily be customized to fit any control box (or similar).

#### Background
I used TUSH and like it very much, but I needed some kind of brackets that I could safely put on top of my Tevo Tornado control box, and I wanted a more stable solution, since TUSH can quite easily fall over. Since I wanted to check out OpenSCAD for some time I simply started to create a less fancy looking spool holder that shares the core features of TUSH.
