Ultimate Bowden PTFE Tube Clamp (no slip and rotation)

Description

This clamp should enhance any standard G1/8 (M10) fitting for 4mm PTFE tubes. It is able to hold any spinning / slipping / moving back and forth tubes. If the tube moves, it can both damage itself being cut with the teeth of a fitting and affect print quality, as you need to set greater retractions. If you have such a problem, this part will do it right without overtightening the tube. <h3>For one fitting you will need:</h3> <ul> <li>print two parts, as one is just a half (print them standing on the wider side with supports).</li> <li>get a sanding paper (i think 120-300 grit should do the best job) and cut a piece about 7x11mm. I used the old paper for the sanding machine.</li> <li>two zip ties.</li> </ul> <h3>Instructions:</h3> <ol> <li>Screw your fitting into hot end radiator or extruder</li> <li>Put the tube in and fix it in place as you normally do</li> <li>Slide one printed piece onto the fitting from the side</li> <li>Wrap the sanding paper around the tube (working side to the tube) and move it to the shallow slot on the inside of the part just like on the photo</li> <li>Slide the second piece and make sure sanding paper is wrapped around the tube properly</li> <li>Tighten the whole part around with two zip ties until they barely move</li> <li>Done :)</li> </ol> On the last photo you can see the result. The tube was pulled after about 7 Hours of printing to take this photo. The teeth of the fitting are just small dents on the tube surface, that means, the tube did not move at all.
