RV Exterior Compartment Door Magnetic Catch

This is a magnetic catch designed to hold open the basement door on a Truck Camper. My camper is a 2023 Northern Lite 10-2, but this might work on other makes and models too (you decide). It is designed to attach to the grab bar, and catch the basement compartment door and hold it open. It's also designed such that if someone is inside the camper and unaware that the hatch door is open, that opening the main door will simply push the compartment door away from the magnet and close the door - so there is no danger of a person getting stuck inside the camper.

The design requires pausing the print at the top of the magnet compartment, so that you can install the magnets and then embed them. I printed the parts that connect to the grab handle in black and the part that connects to the door in white, so they blend with the camper colors. In my photos you see a line where I paused - this should not be there - my printer didn't resume the right temperature after the pause, but if your printer behaves correctly, this should be seamless.

I have a total of 4 embedded magnets here - 2 on the door, and two on the catch. I'm not sure if that is overkill or not, but it seems to work right, so I like it. My magnets were 3mm thick by 12 mm diameter (available on Amazon). Despite the overhang, I didn't use supports, and it came out just fine, but there is an overhang where the magnetic swivel catch connects to the part that attaches to the grab bar. I used 5 screws (all of them stainless steel #4x3/4")

The goal is opening the compartment door and it staying open - requiring only one hand.
