This is a set of parametric vise soft jaws. This model is base on my previous Vise Soft Jaw Design (http://www.thingiverse.com/thing:1376177).
The length and width of the soft jaws can be altered to accommodate any vise. As well the knurling pattern on the front jaws face can also be altered. A V-groove has also been included for holding round materials.
Below are all the dimensions that can be adjusted.
viseLength = 100;
jawWidth = 12.7;
thickness = 6.35;
//knurl pattern settings
knurlAngle = 45;
knurlWidth = 0.5;
knurlDepth = 2;
knurlSpacing = 7;
//v groove size
vGrooveSize = 10;
//Dimensions of magnets
magnetSize = 5.1; //oversize magnet hole slightly to ensure close fit
magnetSpacing = 25;
Edit: The V-groove position can now be adjusted. As well there is an option to choose either circular or cubic magnets.
Use cyanoacrylate glue to bond the magnets to the soft jaws. Make sure to slightly oversize the magnet holes so that they have be easily inserted into your printed parts.
