Magnetic lock in front panel handle for BambuLab X1C

My 3D printer is very interesting with all the lights and movement for my toddlers. I was looking for a door lock for the X1C enclosure, what prevents my toddlers from opening the door. Since I did not find any model on several platforms, I decided to design a door lock by myself. I redesigned the front panel handler from scratch and added a slot for a magnetic key. On the other side of the glass panel, I added a bar with a magnet inside. With the magnetic key you can push or pull the bar, which locks or unlocks the glass front panel.

Printing:

Print out the 4 parts. The handler file and the key file have separate objects inside for coloring. Print the key standing on the small side. This will ensure that the magnet fits well in the plastic part. You may need a brim for the key.

Beside the 3D printed parts you need will need:

Construction:

Remove the original front panel handler.

Insert the round magnet in the bar. You may need a little force to press the magnet in.

Insert the rectangular magnet in the key in the right orientation, again a little force is needed. The rectangular magnet should be repelled from the round one when the white circle of the key is facing to you. You can see afterwards easily if the door is closed (you see the white circle of the key) or open.

Insert the heat threads in the handler.

Put the bar in the bar case. You should see the round magnet.

Screw the bar case with the handler through the glass front panel.

Close the front panel and insert the magnet key in the handler.

Printed my handler in Prusament ASA, white and black.

Feel free to modify or remix the design.
