Hi, here are some of my dockingstations. I have printet 3 Stations. One of these in PLA CF, other two in PLA matt. The docking stations need the magnetic kabel to work perfectly:

Edit: I corrected the PLA CF profile (in my print at different speeds, now at 120mm/s). The white spots on the front of the PLA CF print are only there because I couldn't wait to take the print off. The extruder went back and you can imagine the rest^^
Happy printing :-)
