About this model

The Bambu X1 and P1P have a 4 pin connector on the back usually utilized for the AMS system. I don't have one but wanted to hook up some 24v lighting and a filtered air intake fan using the 4 pin connector. Not needing the other 2 pins, I took a Molex Microfit 3.0 2x2 connector and cut it in half (you can't use the 2 pin connector that is part of the microfit ecosystem because the pins have a particular shape that doesn't allow the 2 pin connector to plug into a 4 pin port). This connector isn't perfect - the pins will not click/lock in place - but it works well enough with just friction holding everything in place. Update: the .stl will likely open in Bambu Studio at 10x normal size - just scale down to 10%. Or you can use the .3mf which has the correct scaling and set for a 0.4mm nozzle…
