The perfect drag chain

Why design another drag chain?
Other models I found all had printing problems, poor design, limited features and/or high friction when bending. I designed this for my MPCNC and will likely use this on my Ender 3 and future coreXY I plan to build.

Features!
Zero friction! very important.
Fast Print optimized.
Wire retaining snap in clip option. It works really well and prints easily.
Every angle optimized for perfect printing on cheep printers.
Zip tie open Chain for more unique ways of securing wire
Bidirectional models available.
