This is a modded extruder bracket I made with a cable holder and expanded hole for filament input tube to be used for flex materials.

In the process I added a cable holder on the side of it as the printbed on the CR-10 tends to rub against the cable when the printbed moves.

In order to print flexible filaments with this, you take a piece of feeding tube (approx 10mm), stick it in the enlarged hole where the filament goes in, then cut the edge in an angle that best possible fits in between the two wheels driving the filament.

Theres already a bracket model on here with that feature and I used it to start with, but the hole for the tube plug was too big and the threading on the plug didnt grip too well and eventually it started to pop out while I was printing.

This model here is NOT a ripoff, stolen or anything like it, I measured the original part using a vernier caliper, then modelled it using Autodesk Inventor.

As not all printers will print with the exact same measures due to different conditions, I included the source (Inventor part) .ipt-file in the archive so you can edit it in case you need to.

Thanks for your design, one comment though, I connected the bowden connector and it doe not thread all the way, is this normal?
I used the spare one delivered with the printer.
I might print a new one with a deeper hole for the connector.
Also, is there an easy way to insert the ptfe tubing in the hole? I struggled to insert mine

I too had the issue with the connector, where it wouldnt grip because the hole was slightly too big, which is basically why i made my own.

However, the tolerances are rather small, so a slight mismatch in stepper adjustments between printers can make it work on one printer and not on the other.

Getting the PTFE tube in the hole can be a somewhat tricky part indeed, the way I did it was by taking a full length tube, twist and press it in to the hole, then make the cut after it was properly inserted.

If you havent done so already, you could also try and check your steppers calibration (steps/mm), on my printer all steppers needed readjustment, some more than others, incl. the extruder stepper.

Finally, if it wont work at still, you could also take the inventor file (I think I added it to the filepool) and edit the hole sizes using inventor or another compatible editor. :-)

thanks, I will try what you recommend

Np, let me/us know how it works out for u; im really curious to know about if you fixed it merely by calibrating the steps/mm. :-)
