Reinforced Spool holder for Prusa i3 - Lasercut frame type fit

This is a spool holder for Prusa i3 Laser cut frame

Tried to print thingy 68329 and it didn't fit.
So did my on design on it. So here it is!

Derived from:
http://www.thingiverse.com/thing:68329
And made for the lasercut frame model:
http://www.thingiverse.com/thing:39889

Changes - fits to the 39889 thingy, bit larger in dimensions - sturdier.
Made a filament guide for this thing too.
