About this 3D model

If you are building a Mini Kossel with an open belt (vs. the vanilla version that uses a closed belt) you will need a way to close it to form a continuous loop. Some design considerations: - holding force - high stiffness to minimize hysteresis - ease of installation - allowing for excess belt length to spill out After several iterations I settled on this type of a design. The SCAD is included and is fully parametric. The STL corresponds to a 6mm wide GT2 timing belt. It should be impossible for the belts to clip unless the belt clip itself deforms, which is why you want a relatively high infill. If your belt teeth are getting squished rather than fitting into the clip then consider increasing tooth_radius in the SCAD. Repo: https://github.com/jcdoll/kossel
