This is a fan button holder for Bambu Lab A1. It is designed to be used in a automation setting.

I use it to automate my Bambu Lab A1 based on the brilliant video of Factorian Design: Automate your Bambu Lab A1 & A1 Mini!. Here is my edited G-code based on his work: github.com/yekta/bambu-a1-gcodes. This G-code moves the printer head to activate and deactivate the button at the end of a print sequence. Please be careful if you are going to use these G-codes and test it throughly and carefully.

The button it holds is called Powermaster IC-190. It has 10mm diameter, 1mm pitch thread (M10). You can use similar buttons but you would need to adjust the distance of the button from the surface which you can do using the STEP or SolidWorks models. Or you can copy the Onshape project below and edit directly.

There is a compartment at the back for keeping a PCB and cables (I'm using a voltage regulator). The holder goes onto the top part of A1. The clips is pretty strong. It's pretty hard to get it on there but once you do it's not going anywhere.

There is also a fan holder that holds the fan which connects to this button: Link to the Fan Holder.
