I did not like the way my brand new FLSUN V400 had the tablet mounted on the bottom of the printer. I decided for me it would be best mounted on the top. I pulled the wire loom back, separated the wires for the tablet then returned the other wires to the original location.

I then got to work on a magnetic mount to keep the tablet secure on the top of the 3D printer.

I used PLA Plus to print it and used 15 - 10mm X 2mm magnets to hold it firmly in place. I left a little wiggle room for different printers and used CA glue with activator to hold them in place. Make sure to get the magnets in the same polarity before gluing them in place.

This holds well to the top but is easy to move it around for the best viewing angle.
