Prusa I3 Spool Holder for 6mm Alu.

Same Story again.. i couldnt find strong and good design then i did.
I used some arched support connections. Arm lenght and height are good fitting for feeding filament without any filament guide. it is working quite good with http://www.thingiverse.com/thing:86463 3 in 1 spool shaft.
Enjoy..
