HyperCube printable X bushing with integrated clamp

This is Parametric Bushing by Dennis Hofmann (https://www.thingiverse.com/thing:2202854) with integrated handles to direct attaching to X carriage. I also added optional gap inside bushing to lower friction.

Generally i always have problem with clamped igus style bushings because they are squeezed and deforming by clamps. Furthermore double standard length bushings are not aligned and wobbling a bit. This bushing solved theese problems.

ABS is not suitable because it sticking to rods. PETG is the best.

Before print adjust theese variables in scad!
* **inner_diameter_in_millimeter**
* **extrusion_width_in_millimeter**
* **number_of_perimeters**
* **number_of_teeth**

//Edit: added bushing with 10.25mm inner and 16mm outer diameter.
