CTC Filament Guide Backwall

Just a small modification of CBikers Thing 634890.

First of all a big thank to CBiker and his, let's say "CTC Bizer Compendium"!
Really a must follow for all those who just started with one of these Chinese Makerbot/Flash Forge clones.
Only, it was driving me mad trying to print this backwall filament guide with my out of the box configurated printer, not having updated any axis guide or firmware to Sailfish.
But having it brand new I was angry about losing warrenty.
So I was thinking to myself, why printing something with rafts and supports, that also does require bought-by fasteners and straps.
That's why I decided to modify this most elegant guiding feature.
I hope, even in your eyes, it didn't loose too much of its elegance.
I'm pretty satisfied with it, since you can print it without using rafts or support and you can directly fix it to the bachwall of your printer.
Just using 4 M3 bolts and nuts.

Since it is a hell of a job to convert STL files back into any modifya
