A pair of replacements clamps to retain your Techzone Huxley bowden cable.There's a test system included in the scad file to verify the diameter of the tube is working before printing the whole thing.The STL is here as an example (it fits my ptfe tube bought from the grrf). You should measure your cable external diameter and use the openscad file instead.1) Measure the external diameter of your bowden cable. Using digital calipers is better if available.2) Open the scad file, set "tube_dia" accordingly and set "test" to 1.3) Print the resulting test piece and verify how it clamps on your tube. Iterate until you're happy with the clamping.4) Set "test" to 0 and print the actual clamps.
