Prusa i2 bar clamps replacement

thingiverse

This project was initiated to replace outdated i2 bar clamps without dismantling the entire printer. The specifications include holes for M3 bolts (3.12mm), rod holes (8.2mm), and nutraps with a diameter of 6.55mm. The dimensions are 30 x 26 x 26 mm. For each clamp, you will need four M3 bolts (30mm long), four M3 nuts, and four M3 washers; however, for clamps adjusted for motors, you may only require three of each. There might be an issue with nuttraps, as the maximum error in printing a 3mm hole is 0.1mm (2.9mm). The OpenScad source is provided, though it is primarily in the author's language with English comments. Please pardon any grammatical errors in this explanation. The printed items use Skeinforge with a layer height of 0.3, Edge Width over Height of 1.6, Infill Solidity of 0.4, and Feed/Flow rate at 30/30, without support.
