Mini Kossel Delta 3D Printer Spoolholder

=> First Off very IMPORTANT!! <=

For a half year now i'm teaching my little brother how to draw in cad.
The rendered pictures is his work.
I must say nice job!
But what do people think? did he pass?
let me know in de comments!

2 weeks ago i bought my self a new 3d printer.
A mini kossel delta to be exact.
This is my third 3d printer and i love the freaking thing!
Lots of calibration, but prints like a dream.
One thing i was disappointed about was the spoolholder.

So i designed my own, and works like a charm.
I presume that every mini kossel is the same and have the same dimensions.
So i did not bother making it adjustable.
But if this is not the case let me know.
