V1E MP3DP v4 — PTFE/Wiring guide with runout sensor mount (CoreXY 2020)

[Update 2023/09/28 Added aza-ptfe-guide-110mm.v4, larger radius to help avoid umbilical sagging and snagging on the XY rails.

Created compact tidy enclosable PTFE guide and gantry wiring setup.  Goal is to be reliable, low drag and not impact quality/speed.  Nice to have PTFE not make a racket slapping against the LID panels.

Typical 1000+ mm/s 3D printer builds seem to be open with massively long lengths of reverse Bowden PTFE towering over the top of the Printer.  However, I wanted a compact setup to help minimize overall height, helping reduce space taken up, and reduce heat energy required/lost.
 

Includes mounting holes for BigTreeTech Smart Filament Sensor (BTT SFS) v1.0 btt-sfs-v1-0-smart-filament-sensor-detection-stuck-blocking-filament-module.  Remove sensor's back plate and mount directly.  Note how the sensor wiring routes down through a channel cutout on the left side.

Includes holes for zip-ties, consider reusable zip-ties.  May be able to use mount without zip-ties given the snug fit.

Ended up with this design after looking at a few different setups, including…

• Niget2002's V1E MP3DP v4 PTFE guide at https://www.thingiverse.com/thing:5968992
• Voron Trident
• Bambu
• Pantheon
• Creality K1

Was cool to see my final setup ended up looking similar to Creality Sermoon D3 Pro before I'd even stumbled across that design.

Created this Mod for my V1 Engineering MP3DP v4 build ( https://www.printables.com/model/282346-mp3dp-v41 ).  May work for other CoreXY printers depending on their belt setup.
