I replaced the black plastic mesh and black shrink tubing around the cables going to my Ultimaker 2 hot end gantry with white versions of both.  Now that I had all that white goodness, those original black bowden-to-mesh-cable clips were an eye sore!  Measured one, modeled it in Sketchup and it came out perfect!  Now you can have any color/material you like for your clips.I printed mine with Faberdashery's Architect's Stone. The color blends nicely with the slightly different shades of white of the other materials. Love the color of that filament! I should have taken a close up photo of a print that came out much nicer. The first image above is flipped upside down and wow!, my first layer was pretty under-extruded!Anyway, the two open circles 'snap' onto the bowden tube just as tightly as the original. I'm very happy with my first YouMagine contribution :)Update:  Having an enclosed print area is bad for PLA parts.  The ambient temps when printing ABS is too high and the clips all melted.  I have since reprinted them in ABS and everything is fine.
