L - Frame Stabilizer. Adjustable stabilizer for prusa i3 single standard frame ( 6 mm/10 mm of thickness).
I designed this structure to reduce vibrations reinforceing the back side of printer adding an aluminium L profile. This solution is applicable to all prusa i3 printers with single standard frame of 6 mm/10 mm of thickness (for me 6 mm aluminium frame).

About 1 x 280 mm aluminium L profile ( section 30 X 20 x 2 mm ) - 1 m about 4-6 euro.
About 2 x 400 mm M8 thread - 1 m about 2-3 euro.

4 x M5 nuts and screws ( 20 mm ).
8 X M8 nuts.
4 x M3 nuts and screws ( 10 mm ) or 4 x self tapping screws.
4 x self tapping screws.
2 x M10 washer.

Washers, a drill and an hacksaw and some keys.

Instruction:
See instructions pictures. It is only required to unscrews two nuts of the printer (the M10 nuts of back side), mount the structure and screw.
Screw the M8 knob by hands !
