Filament Holder Enéas

I made this to put at wall or at a 3d printer steel frame 20x20 or 30x30, you will just need a bolt and a the proper rotating and locking nut...

Ah! You may need do with a drill a bigger hole to fit at frame or wall

Specifications:
Layer 0,3mm
TOP, Bottton and wall 4mm
Infill 40% or nothing...

Be happy!
