Update, I just added 2 new versions a plain version of the end stop switch cover (no logo) and another one with the Dragon Logo but these two has a tie point for the end stop switch wire. Just lock the wire down with a ZIP tie.
Here is my cover for the Ender 3 with the Dragon Logo. You can print the insert in another color and place it inside the cover. Please note that the insert has a hole in the panel. It is there to be the eye of the dragon. I got this idea from https://www.thingiverse.com/thing:2921529 I saw that one and printer it out but I did not like the screws showing in the open area. If you still like that version you can print out the insert and put it inside of that cover. I have also added a SD storage tray version. This tray will fit the CR-10, Tevo Tornado and Ender-3 and maybe a few others. Seems like they are all using the same design more or less. I made the SD card tray version for my Tevo Tornado and will be reprinting it in green. Made with https://www.tinkercad.com
I was asked to add a small hole on the side for the X end stop switch cable. So I added a 5x8 mm hole.
