The Advanced Filtration System (AFS) protrudes quite a bit at the back, and I often have to store my printer in a cabinet. I wanted a way to quickly remove the AFS without having to open the xBuddy box to disconnect the AFS connector from the xBuddy extension board.
For a reliable solution, I opted for the Molex ClickMate connector, just like Prusa does. This project includes a small PCB, 3D-printed enclosure (base and lid), extension cable, and optional magnetic mounting hardware.
What You Get
Quick-connect adapter - Disconnect the AFS in seconds without opening the printer enclosure
Complete design files - CAD models (3MF + STEP), KiCad PCB files, and production-ready manufacturing files
Materials

Easy option: Upload to JLCPCB for cheap assembly (€5-10).
3D Printing
3MF files - Import directly into your slicer (PrusaSlicer, Cura, etc.)
STEP files - For modifications in CAD software
3D Printing Settings
Use the following recommended settings:
Layer height: 0.2mm
Print orientation: Flat sides down (as provided in files)
Support material: None required
Infill: 15-20% (cubic or grid pattern recommended)
Material: PLA, PETG sufficient
Assembly
Prepare 3D printed parts
Insert PCB into base enclosure
Attach extension cable
Connect the Molex ClickMate cable to the PCB connector (Side with the big cutout)
Route the cable like the direct AFS cable was routed to the xBuddy extension board
Connect the other side of the ClickMate cable to the xBuddy extension board
Install optional magnets
Close the enclosure
Mount to printer
Bonus Use
The AFS QuickConnect can also be used as an extender for stepper motors or other connectors if cables are too short.
