IMPORTANT:
 

Please ensure the length of the PTFE tubing inside the printer from the black rubber part at the back to the hot end is EXACTLY 45cm - this is to avoid kinking the tubing when the head moves to the rear right.

Description

When using expensive Capricorn or similar tubing - I was having issues where the tubes were rubbing and wearing against the chain because the stock PTFE tubing guide leaves a lot to be desired. I have tried printing quite a few different clips to re-reroute the PTFE tubing but with limited success. All of the clips I have tried attempt to guide the tubing along the top of the chain. The problem with this is that near the rear right and front right the tubing bunches up and where the tubing enters the hot end it gets horribly distorted.
 

I therefore tried a different approach - routing the PTFE tubing around the outside side of the chain and this clip set is the result. Very simple to install and uninstall, prints all the clips in around 27 minutes and uses less than 10 grams of filament!
At first I also encountered AMS load and retraction issues which most of the other models on here had. By carefully moving and changing the order of the clips I was able to guide the PTFE tube at an angle that the AMS is happy with. Many successful load and unloads completed. The positioning was also designed to keep the PTFE tubing from rubbing against the top glass on printers without a riser.

Printing Instructions.

Print using PETG or above. They can be printed in PLA at your own risk!
Use a brim to make sure they print successfully as they are small parts. You can print without a brim but slow the printer way down.
All other settings can remain as default.
Printed in orange to highlight the clips but would probably look far more awesome in black.

Install Instructions.

The 3mf has the parts laid out from top to bottom in the order deflector, low extradeep, high deep and high shallow.

Please use the picture guide to match which link is which - it's important that the correct clip is placed around the correct link.

Links 2, 4 and 6 - install a deflector
Links 8 and 10 - install a low extradeep
Links 12 and 14 - install a high deep
Links 16, 18, 20, 22, 24 and 26 - install a high shallow

Notes.

Remember to do a full calibration and resonance check as adding the clips may alter the current printer profile.
The original black clip on the chain is not used in this configuration but can be left in place.
The easiest way to attach the clip is to hook the left side in first and then using a squeezing motion snap the right side that has the PTFE guide into place.
To remove the clips (and save your fingernails) hold the PTFE guide part and pull upwards. BE GENTLE or the chain may come apart and need to be snapped back into place.
There is one extra clip of each type in the 3mf file on the right of the plate in case any of the retention clips break but I have not had that problem yet - these can be removed if spares are not needed.
If you find the clips "click" when the print head is near the right side of the build plate I have found that a small strip of the furry side of self adhesive velcro stuck along the right side back half of the printer frame where the chain recesses into stops that completely.

As always any comments and/or feedback is gratefully received.
