Filamente frame holder
I saw the original model, but it can't print in printrbot 1405, now I can.
It is the same than the original one, but is designed for printing in 100x100 bed size(PrintrBot Simple 1405 size)
Maybe is necessary some "super glue" to join the rail.
I added some holes to the rail for attach it in a table
Update: barra_de_sujecion_parte_1_v2.stl , barra_de_sujecion_parte_2_v2.stl
This fit more tightly than last
