i printed all the pieces for this hastily at 0.3mm first layer then 0.35mm, 20% fill, and i increased the print speed to 1.5x. the vice does function to a 'plastic' level of satisfaction! lol. the e-clip was much too weak, and i instead used a metal substitute. the eclip would work if you use the bushings as provided, but using the vice in this way is very sloppy, as the jaw is free to rotate side to side more than i am comfortable with. so, i modified the bushing provided, which is designed to hold the guide rods using friction in the translating block, and increased the inside diameter from 9.0mm to 9.2mm and placed them snugly into the static block. they allow the guide rods to slide to and fro with a good balance of friction and stability. i needed to run a tap down the drive screw, but im sure thats because i rifled it out at near max print speed. haha! 9 little screws needed for the assembly, 3 bolts for mounting to a surface if you like. overall it is really cool! it works really good for jewelry making, electronics and other magnet-sensitive work.
