Ultimaker bowden cable repair

Fix your cable if you had to cut it!
Sometimes my 3mm Plastiks gets stuck in the bowden cable because it has 3,10mm or isn't perfectly round. Since the inner diameter from the cable is 3mm there is no margin.
One plastic got so stuck that it was impossible to remove so i had to cut the tube.
Print twice and use 4x 12mm M3 screws and 4x M3 nuts.
Until i upgrade the Ultimaker with a 4/6mm bowden cable i had to fix it. I first tried with (good) tape and cable ties but since it is TeflonÂ® you don't get a good grip.
Finally some 38mm large and quite thick piece of TesaÂ® did the trick. But it wasn't strong enough to hold against the bending. This is a big problem if you want to change the plastic because the two parts of the tube aren't aligned.
This parts keeps about 20mm of the Tube straight and give the tape more grip.
Note: This is only a emergency fix. After installing it i startet printing new clamps (for a new 6mm tube) for the nozzle and feeder.
