This is a simple magnetic breakout mount for the Openbuilds Mini V-slot 2020 Gantry. I can quickly spin this to work with extended gantry bolts as well if requested.
I chose to use magnets since I didn't want to purchase longer bolts for my gantry... and I'm too lazy to redo my extruder setup :)
This design will allow you to mount a dual RJ45 breakout board onto the back-side of the gantry. I like the design since it keeps it extra tidy by hiding the board and consolidating up to 16 wires into 2 cables.
I am using the 2020 X-Axis upgrade below:

Support is needed to print the 4 round magnet holders. I managed to print without many supports by setting the support angle to over 80% and 100% cooling.
