Prusa i3 one hand leveling and corners

Here there are some accessories for prusa i3 leveling system. Superior corners, spring covers, and knurled nut. I could not get longs m3 screws with hex heads, so in the end I decided on m3 screws with more typical allen heads, fixing them with super glue to the corners.

Be sure of your spring dimensions: Two models are included
-9mm OD, 7mm ID springs
-7,6mm OD, 5,4mm ID springs

Other springs: You can resize SLDPRT files with SolidWorks.
