Threadless Ballscrew (customizable, no backlash)

This is a fully parametric threadless ballscrew design used for linear motion with no backlash! It is based on the original design of MSollack, and a re-write of the thing from RifRaf (http://www.thingiverse.com/thing:124800) . This is a model with dual bearings for higher precision and torque capabilities!

The "stock" v2-1 openSCAD file is designed for common/cheap 608zz bearings. I did a lot of code re-work so hopefully it'll take set of parameters much better than the initial version!

This should be fully customizable, enjoy!
