Creality K1 mod: ultimate chain link

This model solves two well known problems with Creality K1 - the chain sag, which results in scratching the edge of the left wall; and the angle at which the PTFE tube goes into the extruder assembly, which makes pushing the filament through problematic sometimes.

The models I have been finding so far were typically solving one of the problems by introducing two more, eventually forcing you to rebuild half of the printer. Mods for the sake of mods isn't really my way, so I took some effort designing my own solution. It moves the tube bend higher and tilts the chain by 10 degrees, mitigating both of the original problems. On top of that, the design is heavily optimised to enable easy printing without the support enabled.

This model can hardly be called a remix, but it derives some basic measurements from the Creality K1 CAD Model by Henlor - incredible work, hugely appreciated!

You will need

• 3 g of PETG

Printing

• Standard 0.2 mm process

• Print as it is, disable supports and brims

• Ignore the slicer warning about the floating cantilever

Post-processing

• snap-off the designed support rib

Making the best of it

• It might be not necessary, but consider using https://www.printables.com/model/1098972-energy-chain-starter-10mm-lifter-holder-creality-k for the other side of the chain
