Prusa i2 bar clamps replacement

I made this, because I need to replace old i2 bar clamps without take apart almost whole printer...

holes for m3 bolts - 3.12 mm
holes for rods - 8.2 mm
nutraps diameter - 6,55mm

dimension: 30 x 26 x 26 mm

need: (per clamp)
4 x M3 bolts - 30 mm long
4 x M3 nuts
4 x M3 washer

When U need clamp adjusted for motor - U propably need only 3 x bolts, nuts and washers

maybe it can be problem with nuttraps - i can print 3 mm hole with max error 0,1mm (2,9 mm)

I added OpenScad source but it is mainly in my language - but I tried to make comments in english :)

PS: sorry for my english :)
